PART FOR USE IN FUEL

摘要

PROBLEM TO BE SOLVED: To provide a part for use in a fuel that has a low modulus of elasticity and also has a low permeability of a fuel. SOLUTION: The part for use in a fuel comprises a thermoplastic polymer composition which contains (A) a non-fluorothermoplastic resin component and (B) a crosslinked fluororubber component containing one or more kinds of (b) fluororubbers, at least one kind of the fluororubber being (b1) a crosslinked fluororubber, and satisfies the following properties: (1) (A) the non-fluorothermoplastic resin component has a fuel permeability constant of 50 g×mm/m2×day or less, and (2) a ratio (A/B) in% by mass of (A) the non-fluorothermoplastic resin component to (B) the crosslinked fluororubber component is 97/3-50/50.
