描述
Fortron 4332L6 is a glass fiber and mineral reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade is specifically designed for applications requiring improved tensile and flexural properties when compared to other glass and mineral reinforced PPS grades .
As a linear, semi-crystalline PPS, Fortron 4332L6 is relatively impermeable to gases, hydrocarbons, and other liquids compared to other materials. It provides high dimensional stability, low coefficient of friction, low shrinkage, excellent mechanical properties, high continuous use temperature (160°C to 240°C), and very low moisture absorption .
This grade exhibits high hardness, high rigidity, and excellent resistance to corrosion, hydrolysis, heat, oxidation, and paraffin buildup. It shows excellent chemical resistance to all solvents below 200°C, acids, bases, typical and alternative automotive fuels, and petroleum fluids at elevated temperatures . The material is RoHS, PFOS, and PFOA compliant and is suitable for lead-free soldering and metal replacement applications .
The material has achieved BMW GS 93016 automotive specification and carries UL Yellow Card certification (E107854) .
