描述
Fortron 4184L4 is a 53% mineral and glass fiber reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade is recognized as the strongest and toughest glass/mineral reinforced product available in the Fortron PPS portfolio .
The high filler content of 53% (combined mineral and glass) provides exceptional mechanical properties, rigidity, and low creep, making it ideal for high-load applications. It offers excellent heat resistance at high loads, outstanding electrical properties, and inherent flame retardancy without halogenated additives .
As a linear, semi-crystalline PPS, Fortron 4184L4 is relatively impermeable to gases, hydrocarbons, and other liquids compared to other materials. It provides high dimensional stability, low coefficient of friction, low shrinkage (0.3% parallel, 0.6% transverse) , high continuous use temperature (160°C to 240°C), and very low moisture absorption (0.02%) .
This grade exhibits 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 and is suitable for lead-free soldering and metal replacement applications .
