PPS English name: Pheny ??? lenesulfide Weight: 1.36 grams / cubic centimeter molding shrinkage: 0.7% molding temperature: 300-330 ℃. It is an integrated high performance thermoplastic special engineering plastics, its prominent feature is the high temperature, corrosion resistance and excellent mechanical properties. PPS is a sulfur-containing aromatic polymers, linear PPS after more than 350 ℃ crosslinked into a thermosetting plastic, branched-chain structure of PPS thermoplastics. PPS is the US company Phillips in 1971 industrial production in the first, after the patent expires, Japanese companies have begun to development and production. Japanese companies have a typical Japanese Toray, Japan's output stage is greater than US production. Some other manufacturers are mainly concentrated in the United States, Japan and Europe. PPS world's top five producers of Phillips, Toray, Ticona, Polyplastics, a small Japanese ink. Our Tianjin Synthetic Material Research Institute, Guangzhou Chemical Reagent Factory, Sichuan Zigong Chemical Reagent Hebei Institute of Technology Department of Chemical Engineering and Institute of Chemical Engineering, Guangzhou and other units had a few small test, but were unable to stabilize the continuous production. PPS domestic vendors have Shanghai Alliance mold chemical industry by the year 2000, the world of PPS output can reach 50,000 t / a. PPS greatest demand in Japan accounted for 33 percent, North America 32%, Western Europe 19%, Asia-Pacific accounted for 16%. Material Performance: 1, electrical insulation (especially high-frequency insulation) fine, white hard and brittle, falling on the ground with metal sound, light transmittance after the plexiglass, colored water resistance, good chemical stability. It has excellent flame retardancy, non-combustible plastic. 2, the general strength, good rigidity, but crisp, easy to produce brittle fracture stress, impatience benzene gasoline and other organic solvents. Long-term use temperature up to 260 degrees, remained stable at 400 degrees in the air or nitrogen. Through the glass fiber or other reinforcing material modification can be greatly improved impact strength, heat resistance and other mechanical properties also increased, the density increased to 1.6-1.9, smaller mold shrinkage rate to 0.15-0.25% suitable Country resistant parts. insulation and chemical instruments optical instruments and other components. Characteristics: (1) General performance: PPS is a white, high crystallinity, hard and brittle polymer, the relative density of pure PPS 1.3, but will increase after the modification. PPS has a water absorption of small, generally only about 0.03%. PPS is flame retardant, the oxygen index up more than 44%; compared with other plastics, it is a high fire-retardant material (pure PVC oxygen index of 47% in plastics, PSF was 30%, PA66 29% MPPO was 28%, PC 25%). (2) mechanical properties: the mechanical properties of pure PPS is not high, especially in relatively low impact strength. Reinforced with glass fiber will greatly improve the impact strength, the 27J / m increase to 76J / m, increased 3 times; tensile strength increased from 6Mpa to 137Mpa, increased 1 times. PPS high rigidity, rare in engineering plastics. Bending modulus of pure PPS up 3.8Gpa, inorganic filling modification can be achieved 12.6Gpa, increased five times. The rigid PPO known only 2.55Gpa, PC only 2.1Gpa. PPS under load creep resistance, high hardness; high abrasion resistance, wear only 1000 rpm only 0.04g, after filling F4 and molybdenum disulfide will further Be improved; PPS also has a certain self lubrication. PPS mechanical properties of temperature sensitivity can be small (3) Thermal properties: PPS has excellent thermal properties, short term resistance to 260 ℃, and long-term use at 200 ~ 240 ℃; its heat resistance and PI, second only to F4 plastic, which is also rare in the thermosetting plastics. (4) Electrical Properties: Electrical Properties of PPS is very prominent, compared with other engineering plastics, the dielectric constant and dielectric loss tangent values ??are relatively low, and little change in frequency over a wide temperature range and temperature ; PPS arc resistance, and can be comparable with the thermosetting plastics. PPS used in electrical insulation material, the amount can account for about 30%. Applications (1) Automotive Industry: PPS for the automotive industry accounts for about 45%, mainly for automotive functional parts, ignition, heater, thermostat, lamp, bearing; as can replace metal production exhaust valve cycle and pump impeller, a pneumatic signal mediation. (2) electronic appliances: PPS for electrical and electronic industry accounted for 30 percent, which is suitable for ambient temperature higher than 200 ℃ high temperature electrical components; can produce generator and Point on the engine rinse, rinse bracket, starter coil , shield and blade; on the TV, it can be used for high voltage shell and socket, terminal and terminal board; In the electronics industry, manufacturing transformers, choke coil and the relay skeletons and shells, integrated circuit carrier; high frequency performance, manufacturing H-class bobbin and trimming capacitors. (3) Machinery industry: housing, structural parts, wear parts and sealing materials used, there are specific pump, valves, bearings, bearing bracket, piston rings and gears. (4) Textile fibers: used for special industrial dust removal equipment. (5) film / insulating paper: for motor insulation. The main purpose of pps: pps application is its excellent heat resistance as the center, taking into account its friction self-lubricating properties, chemical stability, dimensional stability, flame resistance and electrical insulation properties. Pps can be used in the chemical synthesis industry, transport, storage of materials of reaction tanks, pipes, valves, chemical pumps, etc., can be made in the mechanical center pps impeller blades, gears, eccentric wheels, bearings, clutches and wear parts; material properties : 1, the electrical insulation (especially high-frequency insulation) fine, white hard and brittle falling on the ground with metal sound, light transmittance after the plexiglass, with **** water resistance, good chemical stability?. Has excellent flame resistance? Is non-combustible plastic. Techtron PPS Product Details: 1: Techtron PPS: This material is different from reinforced PPS products, Techtron PPS easily processed into tight tolerance parts. It is very suitable for processing into a corrosive environment structural components or as an alternative at a lower temperature of PEEK material. Techtron PPS color is beige. 2: Techtron GF40 PPS: the material is the most well-known PPS product. Compared Techtron PPS, produced using the molding process, has better thermal properties and dimensional stability, and at temperatures above 220 ° C, but also to maintain its strength. 3: Techtron CF30 PPS: The class material is a self-lubricating, carbon fiber-reinforced PPS, use molding process and production, with a low coefficient of thermal expansion and unparalleled chemical resistance. It is very suitable for the friction member, or a conductive material. 4: Techtron HPV PPS: This material has excellent overall performance, such as exposure to chemicals and high temperature wear resistance, load capacity and dimensional stability.
