描述
Fortron FX20T1 is an unfilled, impact modified polyphenylene sulfide (PPS) grade from Celanese Corporation. This grade features good flowability for injection molding and extrusion, combined with significantly improved toughness and impact resistance compared to standard PPS grades .
The impact modification provides high elongation at break (20%) , making Fortron FX20T1 a more flexible and durable option while maintaining the inherent chemical and thermal resistance of PPS . The good flow allows for filling thin-walled, complex molds with long flow paths .
As a linear, semi-crystalline PPS, Fortron FX20T1 provides high dimensional stability, low coefficient of friction, excellent mechanical properties, and very low moisture absorption (0.02%) . The material is insoluble in all known solvents below 200°C and exhibits excellent chemical resistance to automotive fuels and petroleum fluids . It is inherently flame-retardant.
