描述
Fortron 1120L4 is a 20% glass fiber reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade exhibits excellent heat and chemical resistance, inherent flame retardancy, and high hardness and stiffness at elevated temperatures .
With 20% glass fiber reinforcement, Fortron 1120L4 offers significantly enhanced mechanical properties compared to unfilled grades, including a tensile modulus of 8,550 MPa and a heat deflection temperature (HDT) of 255°C at 1.80 MPa . The material maintains its performance at continuous use temperatures up to 160–240°C and demonstrates outstanding resistance to automotive fuels, solvents, acids, and bases .
Fortron 1120L4 is a linear, semi-crystalline PPS grade that is relatively impermeable to gases, hydrocarbons, and other liquids. It provides high dimensional stability with low and balanced molding shrinkage (0.3% parallel, 0.7% transverse), very low moisture absorption (0.02%), and inherent V-0 flame retardancy at 1.5mm thickness .
