PPS is a kind of special engineering plastics with excellent comprehensive performance.
PPS has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. PPS is widely used as structural polymer materials, and after being filled and modified, it is widely used as special engineering plastics.
At the same time, it can also be made into various functional films, coatings and composite materials, which have been successfully applied in the fields of electronics, electronics, aerospace, automobile transportation and so on.
Domestic enterprises actively research and development, and initially formed a certain production capacity, changed the past completely dependent on imports.
However, there are still some problems in PPS technology in China, such as fewer product varieties, fewer high-function products, and urgent need to expand production capacity, which will be the focus of PPS development in the next step.
The outstanding performance of PPS has good heat resistance, thermal deformation temperature is generally more than 260 degrees, can be used in the temperature range of 180~220℃, PPS is one of the best heat resistance varieties in engineering plastics;
Corrosion resistance is close to tetrafluoroethylene, and chemical resistance is second only to polytetrafluoroethylene. Excellent electrical performance; Excellenmechanical properties; Good flame retardant property.
