描述
Fortron FX75T1 is an unreinforced, impact-modified polyphenylene sulfide (PPS) grade from Celanese Corporation, featuring high melt viscosity suitable for extrusion and blow molding. This grade is specifically designed to provide exceptional toughness and impact resistance, with the highest impact strength among the Fortron FX series, while maintaining the inherent thermal and chemical resistance of PPS.
The high melt viscosity ensures excellent melt strength for extrusion processes, enabling the production of pipes, profiles, films, and blow-molded components with consistent quality. Fortron FX75T1 is recommended for automotive applications, meeting General Motors specification GMW17769P-PPS-T2, and is specifically used for high-pressure pipes and cooling tubes in electric vehicles (EVs).
As a linear, semi-crystalline PPS, Fortron FX75T1 provides high dimensional stability, low coefficient of friction, excellent mechanical properties, creep resistance at high temperatures, and very low moisture absorption. The material is inherently flame-retardant, halogen-free, and exhibits excellent chemical resistance in high-pressure and corrosive environments.
