描述
Fortron FX650T6 is a 50% glass-fiber and mineral reinforced polyphenylene sulfide (PPS) injection molding grade from Celanese Corporation with improved impact and heat shock resistance . This grade is designed to address the brittleness of standard high-filled PPS grades while maintaining exceptional stiffness, strength, and heat resistance .
With 50% glass and mineral reinforcement, Fortron FX650T6 delivers outstanding mechanical performance including a tensile modulus of 12,200 MPa and tensile strength of 130 MPa . The impact modification provides enhanced toughness and thermal shock resistance—the ability to withstand rapid temperature changes without cracking—making it ideal for demanding automotive and industrial applications .
As a linear, semi-crystalline PPS, Fortron FX650T6 provides high dimensional stability, low coefficient of friction, low shrinkage (0.3% parallel, 0.5% transverse), excellent mechanical properties, creep resistance at high temperatures, and very low moisture absorption (0.07%) . The material exhibits excellent chemical resistance to all solvents below 200°C, acids, bases, automotive fuels, and petroleum fluids at elevated temperatures.
