出光PPS C-140SC

出光PPS C-140SC---PPS has high heat resistance in thermoplastic resin. It can be used at 210-235 ℃ for a long time, and can withstand 265 ℃ for a short time. It has no mass loss in NZ or air at 400 ℃. It is completely degraded in 700 ℃ air. However, it still keeps 40% of its original mass in inert gas at 1000 ℃. Its heat resistance is far beyond that of engineering plastics such as PA and pet. Its weather resistance is also very excellent, in the atmosphere is not easy to aging. PPS has excellent rigidity and hard surface. It is a kind of special engineering plastics with metal properties. Its tensile strength is 76.4 MPa at room temperature and 34.4 MPa at 200 ℃, which is equivalent to the tensile strength of polypropylene at room temperature. At the same time, it also has excellent creep resistance and fatigue resistance, low molding shrinkage and good dimensional stability. The adhesion of the coating is far greater than that of epoxy coating which is famous for its good adhesion.
