Product Name:Thermally Conductive PPS (Polyphenylene Sulfide)
English Name:Thermally Conductive PPS (Polyphenylene Sulfide)
CAS No.:25212-74-8
Aliases:Polyphenylene sulfide, PPS, Poly(p-phenylene sulfide), Phenylene sulfide
Molecular Formula:(C6H4S)n
Physical Properties:A crystalline thermoplastic prepared by modifying polyphenylene sulfide (PPS) with thermally conductive fillers; white, hard and brittle. Density 1.3-1.8 g/cm³, molecular weight approximately 4000-5000. It exhibits excellent electrical insulation, low dielectric constant and dielectric loss, and long arc resistance. Its chemical stability is outstanding: except for strong oxidizing acids (such as concentrated sulfuric acid, concentrated nitric acid and aqua regia), it is resistant to almost all acids, alkalis and salts, and is insoluble in any known organic solvent below 175°C. The long-term service temperature can reach 260°C, and it remains stable in air or nitrogen at 400°C. It has excellent flame retardancy, with a limiting oxygen index ≥44; a 0.8 mm thick pure specimen can pass UL94 V-0 rating. It also shows good radiation resistance, withstanding a radiation dose of 1×10⁸ Gy.
Uses:Suitable for high-temperature, high-humidity, strongly corrosive and electrically insulating applications. In mechanical industry, it is used for pump casings, valves, bearings, gears and other wear-resistant structural parts. In electronic and electrical fields, it is used for transformer bobbins, coil formers, connectors, relays and precision insulating parts. In automotive industry, it is used for igniters, carburetor components, exhaust system parts and other functional parts. It is also applied to chemical equipment linings, pipelines, valves and protective coatings for household appliances.
Technical Specifications:
Density: 1.3-1.8 g/cm³; after reinforcement or thermally conductive modification, it can increase to 1.6-1.9 g/cm³.
Mold shrinkage: approximately 0.7% for unreinforced grade; 0.15%-0.25% for reinforced or thermally conductive grade.
Long-term service temperature: 260°C; stable in air or nitrogen at 400°C.
Limiting oxygen index (LOI) ≥44; 0.8 mm thickness can reach UL94 V-0 flame rating.
Thermal conductivity: 1.0-5.0 W/(m·K), depending on the filler system and loading level.
