描述
Fortron LM1140L4 is a 40% glass fiber reinforced polyphenylene sulfide (PPS) grade from Celanese Corporation, recognized as the strongest and toughest product available in the Fortron PPS portfolio .
This grade is laser markable, making it ideal for applications requiring permanent part identification and traceability . It exhibits excellent heat and chemical resistance, good electrical properties, and is inherently flame-retardant . The high hardness and rigidity at elevated temperatures allow for good load bearing performance, and this product has good weldability due to the modest filler level .
As a linear, semi-crystalline PPS, Fortron LM1140L4 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.
The material exhibits excellent chemical resistance to all solvents below 200°C, acids, bases, typical and alternative automotive fuels, and petroleum fluids at elevated temperatures. It is RoHS, PFOS, and PFOA compliant.
