Compounding composition applied to the air cutoff valve for fuel cell vehicle

Abstract

Provided is a thermoplastic resin composition comprising about 50 wt % to about 70 wt % of a base resin consisting of polyarylene ether resin and polystyrene resin in a ratio from about 4:6 to about 6:4, about 20 wt % to about 40 wt % of glass fiber with a sizing agent, about 1 wt % to about 5 wt % of an adhesion promoter or a multifunctional reactive agent, about 0 wt % to about 10 wt % of an impact modifier, and about 0.1 wt % to about 1.0 wt % of a hydrophobic additive, with wt % based on the total weight. The composition exhibits high tensile strength, impact strength, heat deflection temperature, and low cation leaching. Additionally, a method for preparing the composition involves melt-kneading the raw materials and extruding the mixture using an extruder with specific parameters, ensuring a controlled and efficient production process.
