SCOPE The materials defi
3、ned by these specifications are injection molding aliphatic polyketones (PK). Key performance properties include good chemical resistance, low fuel permeation, good abrasion and wear resistance, good impact strength, low moisture absorption, good dimensional stability, and good hydrolysis resistance
4、. These materials have good chemical resistance in fuels, lubricants, brake fluid, engine coolant, transmission fluid, and related automotive fluids. They have good property retention after 1000 hours of heat aging at 110 C for the neat grade and 140 C for the glass-filled grades. 2. APPLICATION The
5、 -A1 specification was released originally for use in an onboard refueling vapor recovery (ORVR) valve. Additionally this material has been used for quick-connect retainers. At the time of this specification development, this material is planned for use on rollover valves, inlet check valves, fuel p
6、ump components, fuel reservoir and flange, and fuel caps. Additional applications may include bearings, gears, and related components in actuator motors, electrical connectors, and functional components in the brake, coolant, and transmission systems. The A2 specification is being released in suppor
7、t of fuel system quick connects, fuel pump housings, and electrical connectors. The A3 specification is being released in support of development of gears, electrical connectors, and fuel system quick connects. These materials are not intended for use in areas with high UV exposure and/or those that
8、require high levels of color retention. 3.

35、ruded sheets or molded discs using a metal rectangular die, with the dimensions 78 X 12 mm. Dry 16 hours in a standard air circulating oven, at 40 +/- 1 C. Weigh to the nearest 0.1 mg and measure thickness to the nearest micrometer. Immerse in fuel in safety glass containers (max. rating 3 bar press
36、ure and approx. 134C) and placed back in the circulating air oven. Monitor weight increase of each specimen at equidistant intervals corresponding to the square root of time. Prior to the weight determinations the samples are to be dried with a tissue. The “out of liquid time per sample” for weight
37、and thickness determination are not to exceed 10 minutes. No specific precautions were taken to prevent evaporation during the measurements. Continue weight monitoring until total absorption is determined (will vary depending on material). The fuel media is to be replenished every 168 hours. *Data estimated for the 15% glass filled grade from data collected from the unfilled and 30% glass filled grades. 5.6 Recycling Codes: A1 PKPK-GF15PK-GF30
