POLY(1,4-PHENYLENE SULFIDE) CAS NO.26125-40-6

1) Processing performance

PPS resin has good fluidity, low melt viscosity, excellent impact resistance, bending, tensile and ductility properties, and can also be processed by injection molding, molding, extrusion and coating. Polyphenylene sulfide resin can maintain a low shrinkage rate in processing, so it is suitable for the processing of precision parts. At the same time, the mutual capacitance of polyphenylene sulfide resin and filler is good, which can strengthen the properties of filler.

(2) Stability performance

The thermal decomposition temperature of polyphenylene sulfide resin is > 430℃ in the air environment, while in the nitrogen environment, there is no significant mass loss below 500℃. Even at the temperature of 1000 ° C, it can still have more than 40% of the initial mass, and PPS has good chemical resistance, and can resist the erosion of acids, hydrocarbons, bases, alcohols, ketones, chlorofluorocarbons and other chemical substances in addition to nitric acid, concentrated sulfuric acid, chlorosulfonic acid, aqua Regis and other strong oxidizing media. However, it is precisely because of its good stability (high temperature and corrosion resistance), it also brings difficulties to the preparation and detection of polyphenylene sulfide solution, resulting in high operating temperatures required for molding processing. At the same time, PPS resin has stable properties under ultraviolet and 60Co rays.
