1 Solef & Hylar PVDF Polyvinylidene fluoride Typical properties

2 Solef and Hylar PVDF A remarkable combination of properties PVDF is a fluorinated semicrystalline thermoplastic which is obtained by polymerizing vinylidene fluoride. This fluorinated polymer has been manufactured and marketed for more than 30 years, using both suspension process (Solef ) and emulsion process (Hylar ) developed and perfected by Solvay Solexis. PVDF, without any additives, has the intrinsic stability inherent to fluoropolymers, even when exposed to harsh environments. It provides the user with a unique combination of properties leading to longer equipment life. The most important properties of PVDF are listed below: Excellent chemical resistance to most aggressive substances and solvents, Excellent mechanical strength and toughness, High abrasion resistance, High temperature capabilities: continuous use service temperature up to 150 C (302 F), Excellent ageing resistance, High purity, Resistance to UV and nuclear radiations, Excellent intrinsic fire resistance, Low permeability to most gases and liquids, Easily meltprocessed by standard methods of and molding, Wide range of rigid and flexible grades available. Besides the PVDF homopolymers, Solvay Solexis offers a wide products range of VF2 HFP copolymers, and VF2CTFE copolymers which stand out for their better cold temperature behaviour. The VF2CTFE range comprises the Solef series, which offers an improved balance between good cold temperature properties and thermomechanical properties of the homopolymers. PVDF is extensively used in the general chemical processing industry, the high purity semiconductor market, and the wire and cable industry. Solvay Solexis today offers a growing choice of PVDF grades which are associated with new applications such as the Oil and Gas industry, Automotive, Building industry, Electronics, Chimney linings, Lithium Batteries, Fuel cells, Food and Pharmaceutical industries. In addition to the Solef and Hylar PVDF resins, Solvay Solexis offers a wide range of other fluoropolymers also easily processed by,, and all conventional processing techniques: Halar ECTFE (copolymer of ethylene and chlorotrifluoroethylene), Hyflon PFA (copolymer of tetrafluoroethylene and perfluoroalkylvinylethers). Relative performance of Solvay Solexis melt processable fluoropolymers Optical properties Processability Flame resistance Thermal rating Surface smoothness Assistance in the selection of the most suitable resin and processing conditions is available through Solvay Solexis' commercial and technical teams.
