PPS materials have excellent properties, especially the PPS composites obtained by modification and filling. PPS has excellent thermal performance, electrical performance, chemical resistance, radiation resistance, flame retardancy and other properties. For example, the limiting oxygen index of pure PPS can reach 44%, and the oxygen index of glass fiber (GF)/mineral filled PPS can reach 53%. The emergence of new materials has received extensive attention. With the continuous development of society, replacing steel with plastic has gradually become a hot trend. After a hundred years of precipitation and development, traditional metal materials have been difficult to create new patterns. The emergence of PPS engineering plastics gives people more choices. Now let's learn about the application of PPS materials.

The application of PPS is centered on its excellent heat resistance, taking into account its antifriction, self-lubricating, chemical stability, dimensional stability, flame retardancy, electrical insulation, dielectric properties and excellent mechanical properties, so that it can be widely used as a non-metallic material with high temperature resistance, high flame retardancy, high rigidity, high electrical performance and high adhesion in high-tech fields such as aerospace, nuclear industry, electronic and electrical industry, food and drug industry. Due to its inherent flame retardancy, PPS is an intrinsic flame retardant material, which can reach a high flame retardant grade without adding flame retardant. Therefore, it is highly praised abroad and selected as one of the eight special materials for space technology. PPS also has a place in the field of civil industry. For example, in the chemical industry, it can make reaction tanks, pipes, valves and chemical pumps for synthesis, transportation and storage of materials; In the mechanical industry, we can make impellers, blades, gears, eccentric wheels, bearings, clutches, wear-resistant parts and transmission components; In electronic and electrical field, we can make transformer frame, high-frequency coil frame, plug, socket, junction frame, contactor drum and various precision parts; In the automobile industry, engine piston rings, exhaust circulation valves, automobile flow valves, etc. can be made.
