The materials defined 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. 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.
