POM characteristics and applications:

Polyformaldehyde is a thermoplastic crystalline polymer. Known as "super steel" or "sai steel", also known as polyoxymethylene. The English abbreviation is POM. Polymers typically obtained from formaldehyde polymerization,Degree of polymerizationNot high and susceptiblePyrolytic polymerization. It can be used as a raw material for organic chemicals, synthetic resins, and also as a fumigant. Polyoxymethylene is a hard and dense material with a smooth and glossy surface, light yellow or white, and thin-walled parts that are semi transparent. The combustion characteristic is easy to burn,Detached fireAfter continuing to burn, the lower end turns blue, causing melting and dripping, with a strong odor of formaldehyde and fishy odor. Polyformaldehyde is a white powder, generally opaque, with good coloring properties. Its specific gravity is 1.41-1.43 grams per cubic centimeter, and its molding shrinkage is 1.2-3.0%. The molding temperature is 170-200 ℃, and the drying condition is 80-90 ℃ for 2 hours. The long-term heat resistance of POM is not high, but it can reach 160 ℃ in the short term. Among them, the short-term heat resistance of homopolymer POM is more than 10 ℃ higher than that of copolymer POM, but the long-term heat resistance of copolymer POM is actually about 10 ℃ higher than that of homopolymer POM. It can be used for a long time within the temperature range of -40 ℃ to 100 ℃. POM is prone to decomposition, with a decomposition temperature of 280 ℃ and corrosive gases occurring during decomposition. Therefore, the mold steel should be made of corrosion-resistant materials.

Mainly in gearsBearing seats and other mechanical components are widely used in the field. It is also applied to audio machines such as video recorders, CDs, LD, MD players, radios, headphones, stereos, OA machines such as printers, keyboards, CD-ROM drives, household appliances such as washing machines, dryers, hair dryers, mechanical components for seat belts, exterior door handles, etcReflectorAutomotive components such as engine compartments, andcameraPrecision parts such as clocks and watches, as well as materials for building materials, toys and stationery such as game consoles.

Automotive industry: used to manufacture half axles on automobilesplanetary gearMats and other materials not only save copper, but also improve service life. It can also be used as a radiator water pipe valve, radiator tank coverWater pump impellerGear housing, carburetor housing, accelerator pedal parts, as well as heater fans, control rods, various switches, bearing brackets, regulator handles, brakes, and washing pumps.

Electronic appliances: can be used for manufacturing electric wrench shells, switch handles, and also for making telephones, radiosRecorderComponents of video recorders, televisions, computers, fax machines, timer parts, tape recorders, etc.

Mechanical equipment: used for manufacturing various gears, rollers, bearingsConveyor beltSpring, cam, bolt, various pump bodies, casing, impeller frictionBearing seatStructural components of mechanical equipment.

Other aspects: used for making water faucets, framed windows, wash basins, water tanks, door curtain pulleys, water meter shells, and water pipe joints. In addition, it can also be used foraerosolPackaging, oil pipelines, components immersed in oil, andStandard resistancePanels, etc.

It is applicable to type of work products, high stress parts, processing materials, plates, strips, tubesStrongHigh load parts with toughness, gears, pullers, bushings, cams, and other wear-resistant applications, mechanical parts that require wear resistance, materials available for machining, general mechanical parts that require good toughness, general mechanical parts that require high rigidity, general mechanical parts that require high rigidity, and applicationsOffice automationEquipment gears, more mold cavities, and thin meat molded products that are less easy to fill.
