描述
Fortron 1140L4 HR is a 40% glass fiber reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation, featuring improved hydrolysis resistance. It is recognized as the strongest and toughest product available in the Fortron PPS portfolio .
The “HR” suffix designates Hydrolysis Resistance, making this grade particularly suitable for applications exposed to hot water, steam, or aggressive coolants—environments where standard PPS grades may experience performance degradation over time .
With 40% glass fiber reinforcement, Fortron 1140L4 HR delivers exceptional mechanical performance, including a tensile modulus of 15,600 MPa and tensile strength of 200 MPa . It exhibits outstanding heat resistance with a heat deflection temperature (HDT) of 270°C at 1.80 MPa, and excellent chemical resistance to acids, bases, and automotive fuels .
The high hardness and rigidity at elevated temperatures allows for good load bearing performance. This product has good weldability due to the modest filler level . Key applications include electronic components (bobbins, lamp housings, brush holders) and automotive parts requiring strength and resistance to aggressive chemicals (heaters, pumps, valves, fuel rails) .
