English name of PPS: Phenylene sulfide Specific gravity: 1.36 g / cm3 Molding shrinkage: 0.7% Molding temperature: 300-330 ° C. It is a thermoplastic special engineering plastic with excellent comprehensive performance. Its outstanding features are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. Linear PPS is cross-linked at 350 ° C to form a thermosetting plastic. Branched structure PPS is a thermoplastic. PPS was first industrialized by Phillips in the United States in 1971. After the patent expired, Japanese companies began to develop and produce. Typical Japanese companies are Toray Corporation of Japan. At this stage, the output of Japan is already larger than that of the United States. Some other manufacturers are mainly concentrated in the United States and Japan. Western European countries do not currently produce PPS. China's Tianjin Synthetic Materials Research Institute, Guangzhou Chemical Reagent Factory, Sichuan Zigong Chemical Reagent Factory, Hebei Institute of Technology and Guangzhou Chemical Research Institute and other units had a small amount of production. At present, domestic PPS agents include Shanghai Lianmo Chemical, By 2000, the world's PPS output could reach 50,000 tons / year. The largest demand for PPS is Japan with 33%, North America with 32%, Western Europe with 19%, and Asia-Pacific with 16%.

(1) General properties: PPS is a white, high crystallinity, hard and brittle polymer. The relative density of pure PPS is 1.3, but it will increase after modification. PPS has a very small water absorption, generally only about 0.03%. PPS has good flame retardancy, its oxygen index is over 44%; compared with other plastics, it is a high flame retardant material in plastics (oxygen index of pure PVC is 47%, PSF is 30%, PA66 is 29%, MPPO is 28% and PC is 25%).
(2) Mechanical properties: The mechanical properties of pure PPS are not high, especially the impact strength is relatively low. After being reinforced with glass fiber, the impact strength will be greatly increased, from 27J / m to 76J / m, which will increase 3 times; the tensile strength will increase from 6Mpa to 137Mpa, which will double. PPS has high rigidity and is rare in engineering plastics. The bending modulus of pure PPS can reach 3.8 Gpa, and the inorganic filler can reach 12.6 Gpa after modification, which is an increase of 5 times. The PPO, known for its rigidity, is only 2.55Gpa, and the PC is only 2.1Gpa.
(3) PPS has good creep resistance and high hardness under load; high abrasion resistance, its abrasion amount at only 1000 revolutions is only 0.04g, and it will be further improved after filling with F4 and molybdenum disulfide; PPS also has Certain self-moisturizing. The mechanical properties of PPS are sensitive to temperature. (3) Thermal properties: PPS has excellent thermal properties. It can withstand short-term resistance to 260 ° C and long-term use at 200 ~ 240 ° C. Its heat resistance is equivalent to PI, second only For F4 plastics, this is also rare in thermoset plastics.
(4) Electrical performance: The electrical performance of PPS is very outstanding. Compared with other engineering plastics, its dielectric constant and dielectric loss tangent are relatively low, and it does not change much in a large frequency, temperature and temperature range ; PPS has good arc resistance and can be comparable to thermosetting plastics. PPS is commonly used in electrical insulation materials, and its amount can account for about 30%.
(5) Environmental performance: One of the biggest characteristics of PPS is good chemical resistance, and its chemical stability is second only to F4; PPS is mostly acid, ester, ketone, aldehyde, phenol and aliphatic hydrocarbon, aromatic hydrocarbon, chlorinated hydrocarbon. Stable, not resistant to chlorinated biphenyls and oxidizing acids, oxidants, concentrated sulfuric acid, concentrated nitric acid, aqua regia, hydrogen peroxide and sodium hypochlorite. PPS has good radiation resistance.

(1) Automotive industry: PPS is used in the automotive industry for about 45% and is mainly used for automotive functional parts; for example, it can replace metal exhaust valve recirculation valves and pump impellers, pneumatic signal conditioners, etc.
等。 (2) Electronic appliances: PPS can be used in the electronic appliance industry for 30%, it is suitable for high temperature electrical components with an ambient temperature higher than 200 ° C; it can manufacture dots, electric brackets and starter coils on generators and engines Shields and blades, etc .; On televisions, it can be used for high-voltage housings and sockets, terminals and terminal boards, etc .; In the electronics industry, manufacturing transformers, choke coils and relay skeletons and housings, integrated circuit carriers; Frequency performance, manufacture H-class winding frame and trimmer capacitor .
(3) Machinery industry: used for housings, structural parts, wear parts and sealing materials, specifically pump bodies, valves, bearings, bearing brackets, piston rings and gears.
