描述
Fortron 6341L4 is a 40% glass fiber reinforced, tribological-modified polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This specialty grade is specifically formulated to provide improved tribological performance—reduced friction and wear—for demanding mechanical applications .
Fortron 6341L4 offers the same mechanical properties as Fortron 1342L4, but with a different tribological adjustment . This makes it an excellent choice for applications requiring a balance of high strength, stiffness, dimensional stability, and enhanced wear resistance.
As a linear, semi-crystalline PPS, Fortron 6341L4 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, creep resistance at high temperatures, a high continuous use temperature (160°C to 240°C), and very low moisture absorption .
This grade exhibits high hardness, 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 and is suitable for lead-free soldering and metal replacement applications .
