Thermoplastic polymer composition and method for producing the same

Abstract

The present disclosure provides a thermoplastic polymer composition comprising a fluororesin (A), a crosslinked fluoroelastomer (B), and magnesium oxide (C), wherein the fluororesin (A) is a copolymer that contains ethylene unit and tetrafluoroethylene unit; wherein the crosslinked fluoroelastomer (B) is obtained by subjecting a fluoroelastomer (b) to a dynamic crosslinking treatment in the presence of the fluororesin (A), the magnesium oxide (C), and a cross-linking agent (D) under conditions for melting the fluororesin (A); wherein the magnesium oxide (C) has a volume-based 10% particle size of 1.0 μm or less; and wherein a mass ratio between the fluororesin (A) and the crosslinked fluoroelastomer (B) ((A)/(B)) is 50/50 to 95/5.
