描述
Fortron FX32T4 is an unfilled, impact modified polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade is specifically designed to provide significantly improved toughness and ductility compared to standard PPS grades while maintaining excellent chemical resistance and inherent flame retardancy .
The impact modification provides high elongation at break (30%) and improved flexibility at high temperatures . The excellent flow characteristics (MFR of 28 g/10 min) enable the molding of complex thin-wall parts with long flow lengths . The material also offers good performance in high pressure and highly corrosive environments, with extended service life of molded parts and low chemical degradation .
As a linear, semi-crystalline PPS, Fortron FX32T4 provides high dimensional stability, good electrical properties, and very low moisture absorption. 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, achieving V-0 rating at 3.0mm thickness .
