描述
Fortron FX40T1 is an unfilled, impact-modified high toughness polyphenylene sulfide (PPS) grade from Celanese Corporation . This grade is specifically designed to provide significantly improved toughness and impact resistance compared to standard PPS grades, making it ideal for applications where durability and reliability are critical.
As a linear, semi-crystalline PPS, Fortron FX40T1 provides high dimensional stability, excellent chemical resistance, and very low moisture absorption . The impact modification allows the material to withstand higher stress and strain without brittle failure, while maintaining the inherent flame retardancy and thermal stability of PPS.
The material exhibits a Charpy notched impact strength of 50 kJ/m² at 23°C , which is significantly higher than standard unfilled PPS grades. This exceptional toughness is combined with a tensile modulus of 2.42 GPa and a tensile strength at break of 48 MPa .
