1 Product Information APEC High-Heat Polycarbonate Resin 1600 (General-Purpose Grade) 1700 (General-Purpose Grade)/1703 (UV-Stabilized Grade) 1800 (General-Purpose Grade)/1803 (UV-Stabilized Grade) Description Apec high-heat polycarbonate is an amorphous, naturally transparent thermoplastic for processing by injection molding or extrusion. Apec resins are a new generation of aromatic copolycarbonates which extend the service range of standard polycarbonate towards higher temperatures. All Apec resins offer an excellent combination of high heat resistance, clarity, and processibility. Different series have been engineered to precisely match individual heat requirements. These series are distinguished by their deflection temperature under load (DTUL at 264 psi), which ranges from 284 F (140 C) for the Apec 1600 series to 324 F (162 C) for the Apec 1800 series. Within each series, there are formulations with standard performance additives. For example, Apec 1705 is the release grade in the 1700 series, and Apec 1803 is the UV-stabilized grade in the 1800 series. Apec resins are available in natural clear, clear tint, and transparent as well as opaque colors. Applications With their unique combination of high heat resistance and inherent clarity, Apec resins are used in a variety of demanding transparent and opaque applications. Automotive applications include lenses, headlight and brakelight reflectors, and turn signal bulb covers. Other applications include lenses for industrial lighting, lamp housings, hair dryer diffusers, contact lens containers, and microwave oven doors. As with any product, use of Apec resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. For medical-device applications requiring biocompatibility and sterilization at high temperatures, Apec 1745 resin can be considered. For further information on this medical grade, please request a product information bulletin from your Bayer MaterialScience representative. General Characteristics of Apec High-Heat Polycarbonate Hydrolytic Stability. Parts molded from polycarbonate absorb only about 0.15% water at room temperature and 50% relative humidity. Dimensional stability and mechanical properties remain virtually unaffected. Even with immersion in water, dimensional changes measure only about 0.5%. Although frequent, intermittent contact with hot water does not harm polycarbonate, continuous exposure to humidity or water at high temperatures (>140 F/60 C) is not recommended due to hydrolytic degradation, which reduces impact and tensile properties. Chemical Resistance. The behavior of Apec high-heat polycarbonate in contact with chemicals is similar to that of standard polycarbonate. Apec resins are resistant to mineral acids, a large number of organic acids, many oxidizing and reducing agents, neutral and acidic saline solutions, some greases and oils, saturated aliphatic and cycloaliphatic hydrocarbons, and most alcohols. It is important to note that Apec polycarbonate is degraded by alkaline solutions, ammonia gas and its solutions, and amines. Apec polycarbonate dissolves in a number of organic solvents, such as halogenated hydrocarbons and specific non-halogenated solvents such as toluene, ethylacetate, methyl acetate, methyl ethyl ketone and tetrahydrofuran. The solubility of Apec resins is gradedependant. Special high purity solubility grades are available for solution applications. Other organic compounds cause polycarbonate to swell or stress-crack, e.g., acetone. Since chemical resistance to various media is dependent on variables, such as concentration, time, temperature, part design, and residual stresses, the above information should serve only as a guideline. It is imperative that production parts be evaluated under actual applications prior to commercial use. Page 1 of 7 Document contains important information and must be read in its entirety.

A desiccant dehumidifying hopper dryer is recommended. To achieve a moisture content of less than 0.02%, hopper inlet air temperature should be 265 F (130 C) and inlet air dew point should be -20 F (-29 C) or lower. The hopper capacity should be sufficient to provide a minimum residence time of 4 hours. Additional information on drying procedures is available in the Bayer brochure General Drying Guide. Processing Apec resins can be processed on commercially available polycarbonate extrusion and injection molding equipment. Generally, appropriate processing conditions are very similar to those used for standard polycarbonate, with the exception that higher melt temperatures are required. Apec high-heat polycarbonates have a higher melt viscosity than standard grades of Makrolon polycarbonate. Accordingly, the melt temperature should be raised depending on the individual series. Typically, nozzles used for processing Apec resin should have larger internal diameters than those used for standard polycarbonate. Injection speed and holding pressure should be kept low. Optimal mold temperatures are between 175 and 250 F (80 and 120 C). Annealing of parts molded from Apec resin is not normally required. If the molding cycle is interrupted, the cylinder temperatures should be reduced to avoid material degradation. Additional information on injection molding is provided in the Bayer publication Apec High-Heat Polycarbonate Injection Molding Guidelines. Typical injection molding conditions for the individual series are shown in the table above. Actual processing conditions will depend on machine size, mold design, material residence time, shot size, etc. The extrusion characteristics of Apec resins are very similar to those of Makrolon polycarbonate. However, higher melt temperatures are recommended depending on the individual series, i.e., between 535 and 645 F (280 and 340 C). Additional information on processing may be obtained from the Bayer publication Makrolon Polycarbonate Extrusion Guide or by contacting a Bayer MaterialScience technical representative.

3 Regrind Usage Where end-use requirements permit, up to 20% Apec resin regrind may be used with virgin material, provided that the material is kept free of contamination and is properly dried (see section on Drying). Any regrind used must be generated from properly molded/extruded parts, sprues, runners, trimmings, and/or film. All regrind used must be clean, uncontaminated, and thoroughly blended with virgin resin prior to drying and processing. Under no circumstances should degraded, discolored, or contaminated material be used for regrind. Materials of this type should be discarded. Improperly mixed and/or dried regrind may diminish the desired properties of Apec resin. It is critical that you test finished parts produced with any amount of regrind to ensure that your end-use performance requirements are fully met. Regulatory or testing organizations (e.g., UL) may have specific requirements limiting the allowable amount of regrind. Because third party regrind generally does not have a traceable heat history, or offer any assurance that proper temperatures, conditions, and/ or materials were used in processing, extreme caution must be exercised in buying and using regrind from third parties. Regulatory Compliance Information Some of the end uses of the product described in this bulletin must comply with applicable regulations, such as the FDA, NSF, USDA, and CPSC. If you have any questions on the regulatory status of these products, contact your Bayer MaterialScience representative or Bayer s Regulatory Affairs Manager in Pittsburgh, Pa. Health and Safety Information Appropriate literature has been assembled which provides information concerning the health and safety precautions that must be observed when handling Apec resins. Before working with any of these products, you must read and become familiar with the available information on its hazards, proper use, and handling. This cannot be overemphasized. Information is available in several forms, e.g., material safety data sheets and product labels. Consult your Bayer MaterialScience representative or contact Bayer s Product Safety and Regulatory Affairs Department in Pittsburgh, Pa. The use of regrind material should be avoided entirely in those applications where resin properties equivalent to virgin material are required, including but not limited to color quality, impact strength, resin purity, and/or load-bearing performance.
