3 common defects in polyphenylene sulfide injection molding, how to treat them?

Polyphenylene sulfide, full name of polyphenylene sulfide, English name polyphenylene Sulfide (PPS for short), is a thermoplastic engineering plastic with a phenyl sulfide group on main chain of molecule. Polyphenylene sulfide has excellent heat resistance, and long-term use temperature is 200℃; it has good chemical resistance, and has excellent chemical properties similar to polytetrafluoroethylene; it also has special rigidity and good blendability with various fillers and other polymer materials. At present, it is the lowest price among high temperature engineering plastics and can be molded by general thermoplastic processing methods.
