描述
Fortron 1140T4 is a 40% glass fiber reinforced, impact modified polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation. This grade is specifically formulated with an impact modifier to provide good thermal shock resistance .
The “T” in the grade designation indicates impact modification, and this grade represents the 40% glass reinforced version of the T-series. Fortron 1140T4 is designed for applications subject to rapid temperature changes where standard high-glass PPS grades may be too brittle and prone to cracking under thermal cycling stress .
With 40% glass fiber reinforcement, Fortron 1140T4 delivers high stiffness and strength, including a tensile modulus of 14,500 MPa and tensile strength of 185 MPa . It exhibits excellent heat resistance with a heat deflection temperature (HDT) of 265°C at 1.80 MPa .
The impact modifier provides enhanced toughness compared to standard 40% glass reinforced PPS grades such as Fortron 1140L4, with Charpy notched impact strength of 14 kJ/m² vs. approximately 10 kJ/m² . The material maintains excellent chemical resistance to acids, bases, automotive fuels, and solvents below 200°C , very low moisture absorption (0.02%) , and inherent V-0 flame retardancy at 0.8mm thickness .
