PPS (PPS) is crystallization type (crystallinity of 55%-65%) of the high rigid white powder polymers, high heat resistance (for using temperature of 240 ℃) and mechanical strength, rigidity, difficult to burn sex, anticorrosion chemical resistance, electrical properties, all the fine resin dimension stability, wear resistance, resistance to creep degeneration, and flame retardancy optimal optimal. Have self-extinguishing RTV silicone compound, up to UL94V-0 level. Under the high temperature and high still keep a good performance. Liquidity is good, easy molding, forming almost no shrinkage concave spot. And all kinds of inorganic packing material has good affinity. Its development shorten the standard thermoplastic materials (such as PA, POM, PET......) And the difference between senior engineering plastic.
PPSCharacteristics: the maximum allowed in the air temperature can be very high in 220 ℃ to continue to work, the short-term can amount to 260 ℃, in the high temperature environment to maintain a high mechanical strength, stiffness and hardness, excellent corrosion-resistant and resistance to hydrolysis performance (currently have not yet found in 200 ℃ can be dissolved the PPS solvent, the inorganic acid, alkali and salt resistance sex is extremely
PPSAdvantage: high mechanical strength. Hardened, and he did an outstanding low wear, impact resistance and resistance to change sex than PSU and PE is better. Accord with standard very good resistance to the OSU antioxidant. And the hydrolysis of sex, can make repeated steam boiling. Fire prevention self-extinguishing RTV silicone compound plastic. High in the temperature, in 220 ℃ high corrosion resistance can be still be under the cloud, can use to 260 ℃ short. The temperature in the buckling strength and room wet when in the ABS if, low shrinkage rate, excellent size and heat stability, physiological use undoubtedly. Faults: do not wear. Low extensibility. And polarity solvent and alcohol contact will become fragile/fracture. Process such as including stress also is easy to break, not with cooling oil processing and cutting.
Application: electronics, electrical: miniature electronic components package, coil skeleton, motor shell, relays, trimming capacitors components. Precision instruments: computers, timer, copy machine, the temperature sensor and various measuring instrument shell and components. Mechanical: pump shell, pump wheels, valve, fan, flow meter parts, flange constructed, universal top. Car: ignition, the clutch, the transmission, gear box, bearing stents, exhaust system components. Household appliances: hot hair dryers, curlers, hair drier implement, marcel device, such as electric meal bao of protection coating and spare parts.
