M90-04 POM as a milky white opaque, a no-side-chain of high-density, high crystallinity of the linear polymer has good overall performance, outstanding fatigue resistance and excellent creep resistance, good electrical properties, etc. .
1. Mechanical Properties: As the POM is a highly crystalline polymer, has a high elastic modulus, high hardness and stiffness. Long-term use in the -40-100 ℃. And resistance to repeated impact, intensity, strength and temperature by the temperature change is small.
2. Thermal properties: POM has a high heat distortion temperature, were clustered into 136 ℃, copolymer of 110 ℃, but because of differences in molecular structure, but acetal copolymer has a higher continuous use temperature, in general, POM long-term effect temperature is 100 ℃, while the acetal copolymer can continue to use the 114 ℃ 2000h, or at 138 ℃ continuous use 1000h. short-term use of up to 160 ℃.
3. Chemical Resistance: The basic structure of POM it is not solvent at room temperature, below the melting point at or near the resin, but also almost no solvents, only few substances, such as perfluorinated C copper, to form a very dilute solution. So in all POM-resistant engineering plastics in organic solvents and oil resistance is very conspicuous. Especially in high temperature conditions are very good corrosion resistance, mechanical strength and size, and little change.
4. Electrical performance: good electrical properties of POM is one of the dielectric constant, independent of temperature and humidity. Different manufacturing process lead to differences in levels of trace impurities in the volume resistance can be brought for an order of magnitude of impact.
5. POM performance deficiencies; the relative density of large, opaque, not acid; molding shrinkage rate is high; melting point of not very high; thermal degradation at high temperatures very rapidly. In the presence of oxygen thermal oxidative degradation also occurs.
Uses
1.the automobile industry: manufacture of automotive pump, carburetor parts, pipelines, power valve, universal joint bearing, motor gears, crank, handlebars, instrument panels, automotive window lift equipment, electrical switches, safety buckle and so on.
2. Machinery manufacturing industry: widely used application of gears, shafts, chains, valves six, stem nut, bearings, convex l wheel, impeller, roller, nozzle, guide, bushings, fittings, and mechanical and structural parts transmission parts.
3. Electrical and electronics, home appliances field; manufacture plugs, switches, buttons, relays, washing machine pulley, shaft and wheel cassette shell, computer housings and televisions, washing machines, refrigerators, telephones, tape recorders, the dish washer various parts.
4. Precision instruments: the manufacture of the shelf support frame, cover the body, the friction plate and watches, cameras, other precision instruments, parts’
5. POM from time to time can be used for corrosion resistance of fire hoses, pencil pen and pen, toys, comb, zipper, mascara sticks and other consumer goods, and so on.
