Special engineering plastics, as the pinnacle of the field of polymer materials, are a class of high-end engineering plastics with characteristics such as high temperature resistance (long-term operating temperature > 150°C), high strength, and corrosion resistance. Their core value lies in achieving metal substitution through unique molecular structure design, playing an irreplaceable role in strategic industries such as aerospace, new energy, and electronic information. Currently, the global industry is undergoing a structural upgrade from general-purpose plastics to high-performance materials. Special engineering plastics, with their revolutionary advantage of "replacing steel with plastics," have become a key material for the transformation and upgrading of advanced manufacturing.

The shrinkage rate of plastic reflects the degree of dimensional reduction in a plastic part after it is removed from the mold and cooled. Factors affecting plastic shrinkage include the type of plastic, molding conditions, and mold structure. Different plastics exhibit varying shrinkage rates. Additionally, the shrinkage rate is significantly influenced by the part's shape, complexity of internal structure, and the presence of inserts.

Polyphenylene Sulfide (PPS), hailed as "plastic gold," is a high-performance engineering plastic known for its exceptional heat and chemical resistance, inherent flame retardancy, and dimensional stability. It is widely used in automotive lightweighting/electric components, Precise electronics, and harsh industrial environments like chemical processing, providing key solutions beyond traditional materials. Choosing PPS means selecting superior reliability, longevity, and a competitive edge.
