Characteristics and applications of PPS PPS under load, creep resistance, high hardness; high abrasion resistance, wear only 1000 rpm only 0.04g, after filling F4 and molybdenum disulfide will further improved; PPS also has a certain self-lubrication. PPS mechanical properties of temperature sensitivity can be small (3) Thermal properties: PPS has excellent thermal properties, short term resistance to 260 ℃, and long-term use at 200 ~ 240 ℃; its heat resistance and PI, second only to F4 plastic, which is also rare in the thermosetting plastics. Welcome to inquire Yu-sheng plastic. Processing methods (1) Injection: to use common injection molding machine, glass fiber reinforced PPS melt index of 50 is appropriate. Injection molding process conditions: barrel temperature of pure PPS is 280 ~ 330 ℃, 40% GFPPS of 300 -350 ℃; nozzle temperature, pure PPS is 305 ℃, 40% GFPPS to 330 ℃; mold temperature of 120-180 ℃; injection pressure, 50-130 MPA. (2) extrusion: a vented extruder, plastic clutch pps process: the feed zone temperature is less than 200 ℃; cylinder temperature of 300-340 ℃, connecting body temperature 320-340 ℃, the die temperature 300-320 ℃. (3) Molding: suitable for large products, pps plastic, using two compression, before cooling, after hot pressing. Preheating temperature hot pure PPS is about 360 ℃ 15min, GFPPS about 380 ℃ 20min; molding pressure of 10 ~ 30Mpa, bearing pps plastic, cooled to 150 ℃ stripping. (4) spray forming: suspended spraying and suspension spray with the powder thermal spray mixing, eccentric pps plastics are the PPS coating to the metal surface, and then through the plastics, quenching and by coating; PPS coating processed at temperatures above 300 ℃, insulation 30min.
