PPS C-600SG日本出光----PPS is a kind of crystalline thermoplastic, which is based on the combination of paraphenylcnc and sulfur atoms. Its texture is fragile. The properties of materials (such as impact strength, arc resistance and leakage resistance) can be greatly improved by adding fillers. Most PPS on the market h***e been mixed with glass fiber (such as 40% or mineral filler / glass fiber mixture). These PPS Composites h***e good mechanical and electrical properties Insulation property, resistance to humidity, chemicals and high temperature (continuous use temperature up to 240 ℃), it has fire resistance, strong texture (comparable to Alcoa), creep resistance, high dimensional stability, and no difficulty in injection molding complex and precise products. It can still maintain the same properties at high temperature. Because of its neat structure and high crystallinity (up to 65%), the products can be used in many fields Finish in a short time
In addition, PPS is a non flammable material with oxygen index elevation (e.g. 47, same as PVC). The oxygen index of gfpbt is 20 and gfpa is 28. Its notched impact strength (enhanced GF grade) is similar to that of PBT, but lower than that of PPO and PC. currently, PPS with higher molecular weight (e.g. Ryton A-100) are ***ailable for sale, with better physical properties (compared with original PPS) and fracture resistance (e.g. when injected into thick wall parts)
