Different in their chemical structure of the molecular chain can be divided into homopolymer acetal copolymer two. The difference is important: POM density, crystallinity, have high melting points, but poor thermal stability, processing temperature range is narrow (about 10 ℃), slightly lower on the pH stability; acetal copolymer density, crystallinity, melting point, the intensity is relatively low, but good thermal stability, not easily broken, and processing a wide temperature range (about 50 ℃), good stability on pH. Engineering plastics with excellent overall performance. Have good physical, mechanical and chemical properties, especially those with excellent abrasion performance. Steel or steel commonly known as race wins, is the third largest generic plastic. Suitable for production of less wear resistant parts, transmission parts, and chemical, instrumentation, and other parts. General performance POM is a smooth, shiny, hard and dense material, yellow or white, thin-walled portion translucent. Combustion characteristics is easy to burn, away from the fire continued to burn, flame yellow top, blue bottom, dripping melted, there is a strong pungent smell of formaldehyde, fish stench. Paraformaldehyde as a white powder, generally opaque, colored, and the proportion 1.41-1.43 g / cc, 1.2 to 3.0% Molding shrinkage, molding temperature 170-200 ℃, drying conditions 80-90 ℃ 2 hours. Long-term heat resistance of POM is not high, but the short-term up to 160 ℃, which homo POM POM copolymer short-term high-heat ratio above 10 ℃, but the long-term heat copolymer POM POM but higher than the homopolymer is about 10 ℃. Long-term use in the temperature range of -40 ℃ ~ 100 ℃. POM easily the decomposition temperature of 240 degrees. Decomposition irritating and corrosive gases. Therefore, the corrosion resistance of the steel mold should use the material. Mechanical properties: POM strength, high stiffness, good flexibility, anti-friction wear resistance. Excellent mechanical properties, strength up to 50.5MPa, specific stiffness up to 2650MPa, and the metal is very close. POM mechanical properties with temperature change is small, compared copolymer POM POM homopolymer change slightly larger. POM high impact strength, but the impact is less than conventional ABS and PC; POM to notch sensitivity, there can drop as much as 90% notched impact strength. POM fatigue strength is very prominent, after 10 alternating loads, fatigue strength up to 35MPa, while the PA and PC only 28MPa. POM and creep resistance similar to PA at 20 ℃, 21MPa, was only 2.3% when 3000h, and little affected by temperature. POM small friction coefficient, good wear resistance (POM> PA66> PA6> ABS> HPVC> PS> PC), limit PV value is large, self-lubricating. POM products on time grinding, easy to produce a noise similar to scream at high loads. Electrical properties: POM good electrical insulation, almost independent of temperature and humidity; dielectric constant and dielectric loss over a wide temperature, humidity and a small frequency range; excellent arc resistance, and kept at a high temperature. POM dielectric strength on thickness, the thickness of 82.7kV/mm 0.127mm, 23.6kV/mm the thickness of 1.88mm. Environmental performance: POM intolerance alkali and oxidizing agents, acid and weak acid has a certain stability. POM solvent resistance, good resistance to hydrocarbons, alcohols, aldehydes, ethers, gasoline, lubricants and weak base, and maintain a considerable chemical stability at high temperatures. Water absorption, good dimensional stability. Purpose: POM high strength, light weight, used to replace the copper, zinc, tin, lead, non-ferrous metal, widely used in industrial machinery, automobiles, electronic appliances, daily necessities, pipes and fittings, precision instruments and building materials sectors POM is extensive. used in the manufacture of sliding, rotating machine parts, do all kinds of gears, levers, pulleys, sprockets, bearings particularly suitable, water valves, precision metering valve, ring and chain conveyor rollers, flow meters, outside the car handles, window cranks and other rotating machinery, pumps gas bearing and impeller off valves, electronic switch parts, tight solid terminal mirror mask, fan parts, heating panels, instrument buttons; tapes bearing; variety of pipes and agriculture irrigation systems and valves, nozzles, taps, bath basin parts; switch keyboards, buttons, audio and video reels; thermostat timer; power tools, garden tools parts; other as surfboards, sailing and various sled parts, watches Micro gear, sports accessories and backpacks with the framework for equipment used in a variety of buckles, fasteners, lighters, zippers, buckles; Medical Devices pacemakers; artificial heart valves, the top vertebrae, prostheses, etc. The company supplies plastic materials POM, brand Dupont Dupont, Model POM.
