描述
Fortron 6165A4 is a 65% mineral and glass fiber reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade offers a unique balance of properties based on its high mineral and glass reinforced composition, with excellent heat resistance under load bearing conditions .
The 65% filler content provides exceptional stiffness and dimensional stability, making Fortron 6165A4 ideal for high-load applications requiring low creep and reliable performance under stress . As with all Fortron grades, this product is inherently flame-retardant .
As a linear, semi-crystalline PPS, Fortron 6165A4 is relatively impermeable to gases, hydrocarbons, and other liquids compared to other materials. It provides high dimensional stability, low coefficient of friction, low shrinkage (0.2% parallel, 0.5% transverse) , high continuous use temperature (160°C to 240°C) , and very low moisture absorption (0.02%) .
This grade exhibits high hardness, high rigidity, and excellent resistance to corrosion, hydrolysis, oxidation, heat, 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 complies with RoHS, PFOS, and PFOA regulations .
