PPS A310M

PPS A310M---PPS is a kind of special engineering plastics with excellent comprehensive properties. PPS has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. It is widely used as structural polymer materials, and widely used as special engineering plastics after filling and modification. 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, aerospace, automobile transportation, etc. In recent years, domestic enterprises have been actively engaged in research and development, and initially formed a certain production capacity, which has changed the previous situation of relying entirely on imports.
