Product Name:Polyphenylene Sulfide (PPS)
English Name:Polyphenylene Sulfide (PPS)
CAS No.:26125-40-6
Aliases:Polyphenylene sulfide, PPS, Polyphenylene sulfide resin
Molecular Formula:(C6H4S)n
Physical Properties:PPS is a crystalline (crystallinity 55%-65%) high-rigidity white powder polymer with excellent heat resistance, mechanical strength, rigidity, flame retardancy, chemical resistance, electrical properties, and dimensional stability. Its melting point exceeds 280°C, heat distortion temperature exceeds 260°C, continuous service temperature reaches 240°C, and long-term service temperature is 220-240°C. It degrades at 700°C in air and retains 40% weight at 1000°C in inert gas. Flame retardancy reaches UL94V-0 rating, with oxygen index (LOI) >57% and self-extinguishing properties. Its mechanical properties are excellent: Rockwell hardness >100 HR, tensile strength >170 MPa, flexural strength >220 MPa, notched impact strength >16 MPa, flexural modulus >3.5×10^4 MPa. It exhibits outstanding chemical resistance; no solvent capable of dissolving PPS below 200°C has been found, and it has strong resistance to inorganic acids, alkalis, and salts. Dimensional stability is excellent, with molding shrinkage <0.0025%, water absorption <0.05%, and low linear thermal expansion coefficient. Electrical properties are excellent, maintaining good performance under high temperature, high humidity, and high frequency conditions, with volume resistivity of 1×10^16 Ω·cm, surface resistivity of 1×10^15 Ω, and dielectric strength >18 kV/mm.
Uses:Used in high-temperature and anti-corrosion coatings, which can be used long-term at 180°C. In the electronics and electrical industry, it is used to make connectors, insulating partitions, terminals, and switches. In the mechanical industry, it is used to make pumps, gears, piston rings, storage tanks, blade valves, watch parts, and camera parts. In the automotive industry, it is used to make carburetors, distributor parts, electronic and electrical components, and sensor components. In home appliances, it is used to make structural parts of video cassette recorders and crystal diodes. It is also used in aerospace and aviation industries.
Technical Specifications:
Melting point exceeds 280°C, heat distortion temperature exceeds 260°C, long-term service temperature is 220-240°C.
