3 Materials of onstruction Note: Properties of plastics and elastomers vary because different compounds of the same material are used for different products and components. The following materials descriptions are of a general nature. hemline should be consulted for material recommendations on specific applications. THERMOPLSTIS Most plastics are made from synthetic resins (polymers) through the process of polymerization. Two main types of plastics are thermoplastics and thermosets. Thermoplastic products are injection moulded or extruded from compound material processed under heat and pressure. (Polyvinyl ) The largest selection of hemline valves and controls are moulded in. This rigid gray colour material is unplasticized polyvinyl chloride. is formed by the polymerization of the vinyl chloride monomer. Unplasticized or -U has excellent mechanical and chemical resistance properties at low cost. The working temperature range of valves is 0 to 60 (30 to 140 F). Vinyl is plasticized. The added plasticizer produces a flexibile material for such products as tubing, but offers poor chemical resistance. The used for hemline valves is identified by cell classification number as per STM Standard D Suffix refers to the highest chemical resistance rating. Most other valves as well as pipe and fittings have only a chemical resistance rating. The special compound used in hemline valves resists attack of most acids, strong alkalais, salts and many other chemicals. High chemical resistance of this material allows its application on aggressive services such as 98% H2 SO4, dry chlorine and low pressure wet chlorine gas. is attacked by chlorinated hydrocarbons, ketones, esters and some aromatic compounds. It can be used on solutions containing up to 00 ppm solvents. hemline valves are non-toxic. They meet S standard for toxicity and NSF/NSI Standard 61 for contact with drinking water. They are resistant to damaging effects of sunlight and weathering, thus painting is not necessary. (hlorinated Polyvinyl ) is that has been chlorinated via a free radical chlorination reaction. It is similar to in chemical resistance. Mechanically it is more ductile than. It s main difference is higher working temperature ratings and is therefore used where temperatures are too high for or when an extra margin of safety is required. Valves are suitable for applications from 0 to 95 (30 to 200 F). The compound used for hemline valves is classified as as per STM D The suffix denotes conformance to the highest chemical resistance rating. Most other valves as well as pipe and fittings have only a chemical resistance rating. The compound is nontoxic, conforming to S toxicity standard (Pigmented Polypropylene) Polypropylene () is a thermoplastic polyolefin made from the olefin propylene. more modern term for polyolefin is polyalkene. hemline offers piping systems, valves and controls normally in pigmented. The addition of grey-beige pigment prevents degradation due to ultraviolet light penetration. is used in a wide variety of applications from acids and alkali s to organic solvents as well as pure water. is one of the best materials to use for systems exposed to varying ph levels, as many plastics do not handle both acids and bases well. It is excellent on acids such hydrochloric and phosphoric acid but unsuitable on strong acids like concentrated nitric, also chlorinated hydrocarbons, aromatic compounds and high concentrations of free chlorine. is ductile at ambient temperature and has good impact strength. It also has good thermal stability up to 90 (194 F), higher than that of other thermoplastics such as and HDPE. It is light weight. The specific gravity is 0.91 compared to 1.4 for. It s abrasion resistance is good, much better than that of. This is a feature of hemline butterfly valves which have discs as standard. hemline pipe and fittings weld together very well using either butt or socket fusion. The pressure losses in piping systems are lower than metal because of the smooth inside surfaces of the pipes. This property also minimizes or eliminates deposits or bacterial growth. is a poor conductor of heat, i.e. is a good insulator. hilled or hot water systems in often require no insulation. is very inert and relatively inexpensive, thus popular for high purity water systems. The standard pigmented material is normally used. Special grades include U- (unpigmented, natural) translucent material sometimes preferred for pure water systems, pigmented black for the highest resistance to UV light, flame retardant grades to meet building code requirements, and electro-conductive grades for volatile media. Polypropylene is available in two grades: D 41, produced from 0% propylene monomer. -H is the most widely utilized. It offers a high strength to weight ratio and is stiffer and stronger than the copolymer grade. Piping is normally -H. a few hemline valves are also -H. The working temperature range of -H back pressure valves for example is to 70 (50 to 158 F). impact strength, is tougher and more durable than -H. opolymer polypropylene has better stress crack resistance and low temperature toughness than homopolymer at the expense of small reductions in other properties. Most hemline valves and all the pipe fittings are (194 F) for diaphragm valves. U- (Unpigmented Polypropylene) U- is produced from high-purity virgin random copolymer. hemline offers pipe, fittings and valves in unpigmented. U- shows excellent purity levels when tested in standard static leach tests (better than high-purity ) and has a superior surface quality, purity water systems. It is suitable as piping for high purity water systems, compliant with USP lass VI for pharmaceutical high purity applications. It is also approved by the FD for contact with food. The disadvantage of U- is it will degrade if exposed to UV light (sun light). HEMIL RESISTNE GUIDE 3

It has many superior properties as a thermoplastic. has excellent chemical resistance against halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, organic solvents and oils. is not resistant to hot bases. has much higher abrasion resistance than other thermoplastics. hemline s butterfly valves with optional discs offer extended life on abrasive applications. (Polyvinylidene Fluoride) It has remarkable strength over the largest working temperature range. to 212 F) and up to 120 (250 F) for diaphragm valves with a bonnet. s impact strength is over twice that of. The valves and piping will withstand mechanical abuse at sub-freezing temperatures. is a pure polymer without UV stabilizers, thermo stabilizers, softeners, lubricants or flame-retardant additives. It the preferred choice of piping material for ultra-pure water and high purity chemicals in the semiconductor industry. is non-toxic, imparts no odours or tastes into the fluid. It is compliant with USP lass VI for pharmaceutical high purity applications and conforms with FD regulations as outlined in Title The anadian Food Inspection gency recognizes hemline s for use in any food application by Letter of No-Objection. Gas permeability of is extremely low. gas permeability barrier is available on most hemline diaphragm valves. It is a backing to the PTFE diaphragm and has proven to increase the life of diaphragm valves on chlorine and strong acid services. offers excellent fire protection without flame-retardant additives (V-O rating according to the UL-94 vertical flame test) and during combustion has only a slight amount of smoke development. It has high resistance to the damaging effects of UV (sun light) and gamma radiation. ETFE (Halar ) ETFE is a durable copolymer of ethylene and chlorotrifluoroethylene (TFE). hemline offers butt fusion metric pipe and fittings in ETFE, commonly known as Halar. ETFE shares with excellent properties such as high chemical resistance, wide application temperature range, good UV resistance (i.e. unaffected by sunlight long term), excellent abrasion resistance, smooth inner surfaces (low pressure losses, resistant to deposits or bacterial buildup), excellent insulating properties and low permeability. It is extremely inert and the material is natural, without any additives or pigment. It is suitable as piping for high purity water systems, compliant with USP lass VI for pharmaceutical high purity applications. ETFE has a working temperature range up to 95 (200 F). Pressure ratings are higher than for but lower than for. ETFE has excellent chemical resistance (i.e. not subject to chemically induced stress cracking) against halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, organic solvents and oils. ETFE surpasses in resistance to strong bases and is the best material for handling sodium hypochlorite even at high temperatures. ETFE is not resistant to hot amines, sodium or potassium. ETFE offers excellent fire protection without addition of flame-retardant additives. It has a V-O rating according to the UL-94 vertical flame test. PE (Polyetheylene) Polyethylene is the polyolefin produced by polymerizing the olefin ethylene. The ball in a hemline avity Free ball valve is made of PE. They withstand abrasion better than. PSU (Polysulfone) Polysulfone is a thermoplastic polymer containing a sulfonyl functional group (-SO2-) attached to two carbon atoms. It is offered as a tube material for hemline variable area flow meters. It offers high impact strength, high dimensional stability and good optical transparency, all important for accuracy and easy reading of the flow meters. Working temperature range of the PSU flow meters is 0 to 90 (32 to 194 F) depending on end and nut materials. While the standard tube flow meters are not recommended for gases, PSU ones are. It is also more suitable for high purity water applications. The chemical resistance is good generally, but lower than that of. P (Polyamide) Polyamide is a polymer containing monomers of amides. There are a number of polyamide families. Polyamide is a tube material for hemline variable area flow meters. It offers high impact strength, high dimensional stability and excellent optical transparency. The special grade to P used for flow meters has very low water absorption rate. These properties are all important for accuracy and easy reading of the flow meters. P tube flow meters may be used on pressurized gases, whereas cannot be. Working temperature range of the flow meters is 0 to 75 (32 to 167 F) depending on end and nut materials. This is higher than for. resistance is relatively poor compared to, so applications generally are water or only mildly corrosive chemicals. 4 HEMIL RESISTNE GUIDE

5 Materials of onstruction THERMOSETS Thermosets are polymers that irreversibly cure. The curing process transforms the resin into a larger molecular weight plastic by a crosslinking process. The process is initiated through heat, generally above 200 (392 F), through a chemical reaction (two-part epoxy is an example), or irradiation. Due to the three dimensional network of bonds (cross-linking), thermoset materials are generally stronger than thermoplastic materials and have higher temperature ratings. PDPD (Polydicyclopentadiene) PDPD is a polyolefin thermoset polymer which is formed through the polymerisation of dicyclopentadiene (DPD). It is used for hemline butterfly valve bodies from 16 to 48 sizes and air release valves. has excellent corrosion resistance, similar to that of and high tensile strength which translates to high valve working pressures. PDPD body butterfly valves offer higher working pressures than those with bodies at the same price. For example a 20 or 24 Type 75 butterfly valve at 30 (86 F) is 1 psi rated with PDPD body and 50 psi rated with body. Impact strength and dimensional stability is also high. FRP reinforcement in a thermoset polymer, usually vinyl ester resin. hemline can be provided for extremely high abrasion resistance in dirty corrosive gas handing applications. Fire retardants are always incorporated for the hemline damper butterflies. GRP (Glass Reinforced Plastic) VE-F VE-F is a proprietary composite thermoset material. It is composed of vinyl ester filled with % carbon fiber and % glass fiber. It is the body material of hemline s hemvalve TFM (PTFE) lined butterfly valves. VE-F has high temperature rating of 130 (266 F), and high tensile strength for high valve working pressures. It has high impact strength even at low temperatures. ll these properties mean durability and safety in severe and difficult chemical applications. FLUOROPOLYMERS Fluoropolymers are fluorocarbon based polymers with multiple strong carbon-fluorine bonds. They are characterized by a high resistance to solvents, acids, and bases. They have high application temperature ranges. PTFE (Polytetrafluoroethylene) PTFE is almost totally insoluble and chemically inert. It has high temperature resistance. all seats of PTFE have natural lubricity. hemline diaphragm valves with PTFE diaphragms and PTFE bonded flange gaskets are suitable for the most severe chemical resistance applications. PTFE s weakness is that during the forming process the powder raw material cannot flow, so the finished material is left with some microporosity. This allows it to cold flow or creep under conditions of pressure and temperature. The microporsity also reduces the polymer s permeation resistance. hemline PTFE diaphragms are supplied standard with gas barriers to avoid permeation problems which may reduce the diaphragm life. Newer fluoroplymers such as PF and TFM were developed to overcome PTFE s weak properties. PF (Perfluoralkoxy) Perfluoralkoxy (PF) is a fully fluorinated polymer with the same chemical resistance and high temperature performance as PTFE. The big difference is that it is melt process able. PF can be extruded to make pipe or tubing, or injection molded for tube fittings. It has much lower porosity than PTFE and is translucent instead of opaque white. Mechanically it is stronger. The threads in a moulded PF tube fitting are vastly superior in durability and strength compared to the threads machined on a comparable PTFE fitting. pplication temperature is to150 (300 F). hemline recommends PF as the best choice of fluoropolymer tubing. Like PTFE and TFM the PF fluoropolymer is made from tetrafluoroethylene (TFE) and perfluoropropylvinyl ether (VE) monomer units. However, it is polymerized with a higher percentage of the VE comonomer; as much as 3 to 4% compared to <1% for TFM PTFE. This increases polymer-chain entanglement at lower molecular weight levels and makes it melt process able. FEP (Fluorinated Ethylene Propylene) FEP is a melt-process able fully fluorinated polymer with similar chemical resistance as PTFE and PF and similar low porosity and translucency as PF. FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene (TFE) resin. FEP is less expensive than PF tubing but the temperature rating is not as high and mechanical properties not as good. onvoluted FEP is usually chosen for the outer tubing of dual containment PF tube systems. FEP is not used for moulding fittings. TFM (modified PTFE) TFM is a modified form of PTFE. It s chemical and temperature resistance is the same as standard PTFE but TFM can be welded together, or to PF parts. lso porosity is lower, tensile strength is higher, and cold flow is less. The seats of the hemvalve, all-fluoropolymer lined butterfly valves are made of TFM. It is a tetrafluoroethylene (TFE) polymerized with less than <1% perfluoropropylvinyl ether (VE) to produce a slightly higher density molecular structure with side chain branching. This branching increases polymer-chain entanglement, slightly lowers molecular weight, and reduces voids as well as warpage of the material under pressure. ompared to standard PTFE, TFM PTFE has higher permeation resistance which means better resistance to aggressive chemical, less cold flow or creep which means longer life for a butterfly valve seat for example and smoother surfaces which translates to better abrasion resistance and lower particle generation in high purity services.

6 Materials of onstruction ELSTOMERS (Ethylene Propylene Diene Monomer) is a type of synthetic rubber, a cost effective elastomer used D The M class includes rubbers having a saturated chain of the polymethylene type. has excellent chemical resistance on the great majority of applications including acids, alkalis, salts and many others at temperatures up to 90 (194 F). is weak on organic compounds and cannot be used on fats and petroleum oils. hemline valves seals of meet S standard for nontoxicity. FKM or FPM ( Viton Fluorocarbon Rubber) FKM (or FPM) is a fluoroelastomer, polymerized from vinylidene fluoride (VDF) and hexafluoropropylene (HPF). Other FKM types include other additional monomers. Viton is more expensive than so is usually chosen as an alternate elastomer when required. It is a durable material, many aliphatic and aromatic hydrocarbons is excellent. FKM/FPM is weak on sodium hydroxide. It is usually offered as a standard seal material for valves because s temperature rating is lower than that of, whereas FKM s maximum temperatures match or exceed those of. services. butterfly or diaphragm valve with FKM- seat or diaphragm can work in services where usually only expensive all-ptfe lined valves can. Elastomer seated valves usually have longer cycle life than those with PTFE seals. offers better chemical resistance on inorganic acids than standard FKM. The hemline chemical resistance guide shows ratings for hydrochloric, nitric and sulphuric acids. butterfly or diaphragm valve with FKM-F seat or diaphragm can work in services where only all- PTFE lined valves are normally selected. Elastomer seated valves usually have longer cycle life than those with PTFE seals. PE (hlorinated Polyethylene) PE is a high performance synthetic rubber material renown for long life in outdoor membrane applications (pools, fountains, roofs, etc.). s a seal material for hemline valves it has found to be superior to all other elastomers on sodium hypochlorite. It resists hypochlorite up to full strength (13%). all valves supplied with PE seals are very price competitive on this service. (crylonitrile-utadiene opolymer, abv. NR) Nitrile (formerly referred to as una-n) has high chemical resistance to oil and petroleum but is weak on oxidizing media i.e. acids. Nitrile has excellent abrasion resistance and is less expensive than FKM/FPM. It is often chosen as a seat material for hemline butterfly valves in landfill applications and for abrasive slurry applications. It is an excellent alternative to FKM/FPM (Viton ) for petroleum based services. flas flas is a copolymer of tetrafluoroethylene and propylene (TFE/P). It offers excellent chemical resistance to strong acids and bases and excellent oil resistance. It is used as an alternate o-ring material in hemline valves where higher chemical resistance than FKM/FPM is required. It has high heat resistance making it a good choice for ball valves seals. 6 HEMIL RESISTNE GUIDE
