We specialize in customizing all kinds of non-standard electrical and electronic equipment POM gasket POM washers. Stable shape and size, fast delivery. Can be used in mobile phones, computers, televisions and various electrical products, equipment, screw gaskets, sealing gaskets, etc.

Physical and chemical properties of POM polyformaldehyde:

POM is a linear polymer with no side chains, high density and high crystallinity, and has excellent comprehensive properties. POM has good oil resistance, good solvent resistance, resistance to hydrocarbons, alcohols, aldehydes, ethers, gasoline, lubricants, etc., and can maintain considerable chemical stability at high temperatures. It is not resistant to oxidants and acids but has a certain stability to enoic and weak acids. It is not resistant to strong alkalis and sunlight.

POM is a smooth, shiny, hard and dense material with a pale yellow or white color. It can be used for a long time in the temperature range of -40-100 ° C. Its abrasion resistance and self-lubrication are also superior to most engineering plastics. Tensile strength of 70MPa, low water absorption, and good dimensional stability. These properties are better than nylon. Polyoxymethylene is a highly crystalline resin. It is the toughest of thermoplastic resins and has good creep resistance even at low temperatures. Variable properties, geometric stability and impact resistance. High heat resistance, bending strength, fatigue resistance, high abrasion resistance and electrical properties. Specific gravity 1.43, melting point 175 ° C, tensile strength (yield) 70MPa, elongation (yield) 15%, (fracture) 15%, impact strength (unnotched) 108KJ / m2, (with notch) 7.6 KJ / m2
