r, >The scientific name of polyoxymethylene is polyoxymethylene (abbreviation), also known as Saigang and special steel. It is obtained by polymerizing formaldehyde and other raw materials. (polyoxymethylene homopolymer), C (polyoxymethylene copolymer) are high-density, high-crystallinity thermoplastic engineering plastics. It has good physical, mechanical and chemical properties, especially excellent friction resistance.
<:rr, , Polyoxymethylene is a high-density crystalline polymer without side chains and has excellent comprehensive properties.
<:rr, , Polyformaldehyde is a hard and dense material with a smooth and shiny surface, light yellow or white, and can be used for a long time in a temperature range. Its wear resistance and self-lubricating properties are also superior to those of most engineering plastics, and it also has good oil resistance and peroxide resistance. Very intolerant to acid, alkali and ultraviolet radiation. (Adding additives can greatly improve its UV resistance level)
<:rr, , Polyacetal plastic is another excellent resin variety developed after nylon, with excellent comprehensive properties.
<:rr, , Polyformaldehyde has good resistance to solvents, oils, weak acids, weak alkali and other properties. Polyformaldehyde has high hardness and steel, high resistance to creep and stress relaxation, excellent wear resistance, self-lubrication, and fatigue resistance
<:rr, , Polyformaldehyde is a kind of material with no side effects. A linear polymer with chain, high density and high crystallinity, which has excellent comprehensive properties. The tensile strength of polyformaldehyde can reach up to 100℃, and it can be used for a long time at ℃. The embrittlement temperature is ℃, and the water absorption is small. However, polyformaldehyde has poor thermal stability and poor weather resistance, and will age if exposed to the atmosphere for a long time.
<:rr, , The mechanical properties of polyformaldehyde are quite good. It has high strength, elastic modulus, small friction coefficient and good wear resistance. Polyoxymethylene is also highly resistant to creep and stress relaxation.
<:rr, , POM has good dimensional stability and very low water absorption, so the impact of water absorption on its mechanical properties can be ignored. Polyoxymethylene has good dielectric properties, and its dielectric constant and dielectric loss tangent change very little over a wide frequency and temperature range.
<:rr, , Polyformaldehyde has poor heat resistance and is easily degraded to release aldehyde at the molding temperature. Stabilizers are generally added during granulation. If there is no stress, polyoxymethylene can be used for short-term use at ℃, and its long-term use temperature is ℃.
<:rr, , Polyformaldehyde has poor weather resistance, and its general performance will decline after atmospheric aging. However, its chemical stability is very superior, especially to organic solvents, and its dimensional changes and mechanical property reduction are very small. However, it has poor corrosion resistance to strong acids and strong oxidants such as nitric acid and sulfuric acid.
<:rr, , Polyoxymethylene has high tensile strength, low water absorption, dimensional stability, and gloss. These properties are better than nylon. Polyoxymethylene is a highly crystalline resin and is the toughest among thermoplastic resins. . It has high heat resistance, bending strength, fatigue resistance, excellent wear resistance and electrical properties.
<:rr, , has a very low friction coefficient and good geometric stability, and is particularly suitable for making gears and bearings. Because it also has high temperature resistance, it is also used in pipeline components (pipeline valves, pump housings), lawn equipment, etc.
