POM is an abbreviation for polyoxymethylene, and POM belonging to organic chemistry is a high density polymer. Therefore, POM is also known as cold steel, and POM is also called special steel. POM is a high-density, high-crystallization thermoplastic engineering plastic. POM has good physical, mechanical and chemical properties. POM also has a prominent feature, that is, POM has intentional friction resistance. What is the overall performance of POM? Below list the characteristics of POM plastic:
1, POM has a very low coefficient of friction and geometric stability, POM plastic is particularly suitable for the production of gears and bearings.
2, POM has high temperature resistance, so POM is also used in pipeline devices.
3, POM is a tough and elastic material, POM still has good creep resistance even at low temperatures, POM has good geometric stability and impact resistance.
4, the high degree of crystallization of POM leads to its high shrinkage, POM plastic can reach 2% to 3.5%. POM has different shrinkage rates for a variety of different reinforced materials.
POM is a crystalline plastic. The melting point of POM plastic is obvious. Once the POM reaches the melting point, the viscosity of POM plastic melt decreases rapidly.
POM is a crystalline plastic, POM has a good overall performance, POM is the hardest in thermoplastics, POM is one of the most closely related metals in plastics, POM tensile strength, POM bending strength, POM fatigue resistance The strength and the wear resistance and electrical properties of the POM are excellent, and the POM can be used for a long period of time between 40 degrees and 100 degrees.
POM is an ideal engineering plastic that can partially replace metal materials such as copper, cast zinc, steel and aluminum. Therefore, POM should be used in a wide range of applications. POM is a typical product of plastic strip.
POM with many excellent characteristics has excellent performance in each field. Therefore, the demand for POM is very large. POM has a good market prospect. With the rapid growth of construction economy, POM is constantly applied in construction with its own advantages. Expansion, POM faucet, POM window frame, POM wash basin, POM water tank, POM curtain pulley, POM water meter housing and POM water pipe joint. POM is also used to make POM wrenches because of the high insulation resistance of POM. POM is also widely used in computer and fax machines.
