描述
Fortron 1342L4 is a 40% glass fiber reinforced, PTFE-modified polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade is specifically designed as a low-wear tribological grade, ideally suited for bearings, gears, and other sliding friction/wear applications .
The PTFE modification provides significantly improved friction and wear properties compared to standard glass reinforced PPS grades . This makes Fortron 1342L4 an excellent choice for moving parts requiring self-lubrication and long service life under friction conditions.
As a linear, semi-crystalline PPS, this grade 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% flow, 0.5% transverse) , excellent mechanical properties, creep resistance at high temperatures, a high continuous use temperature (160°C to 240°C), and very low moisture absorption (0.02%) .
This grade offers high hardness, high rigidity, and 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 .
