Manufacture of hard acetal POM plastic sheet 1mm-30mm black engineering plastic acetal plastic

POM board has high mechanical strength and rigidity, excellent wear resistance, extremely low moisture absorption, and outstanding dimensional stability.

‌POM (polyoxymethylene) is a high-density, high-crystalline linear polymer with many unique physical and chemical properties, which makes it widely used in many fields. ‌‌

Physical properties
POM has high strength, high rigidity and high wear resistance. Its tensile strength can reach 70MPa, and its hardness, rigidity and wear resistance are very good. The density of POM is usually between 1.41-1.43g/cm³, and its water absorption is relatively low, generally 0.2%-0.5%, which allows it to maintain good dimensional stability even in humid environments.

Chemical properties
POM has good corrosion resistance to many organic solvents, acids, alkalis, and salts, but is not resistant to strong acids and strong oxidants. Its good solvent resistance and electrical insulation make it widely used in electrical and electronic fields.

Mechanical properties
POM has excellent fatigue resistance and dimensional stability, low thermal expansion coefficient, and is suitable for precision manufacturing. It has good self-lubricating properties and a low friction coefficient, and is suitable for occasions where friction and wear need to be reduced.

Application fields
POM is widely used in the automotive industry, machinery manufacturing industry and electrical and electronic industries due to its excellent performance. In the automotive industry, POM is used to manufacture automotive pumps, carburetor parts, oil pipelines, power valves, universal joint bearings, motor gears, etc. In the machinery manufacturing industry, POM is used for transmission parts such as gears, drive shafts, valves, bearings, etc. In addition, POM is also commonly used to manufacture electrical insulation parts, sockets, switches, connectors and other electronic components.

Modification direction
POM can be modified by filling modification and glass fiber reinforcement to improve its mechanical properties and dimensional stability. Filling modification can reduce the cost of raw materials, while glass fiber reinforcement can improve the mechanical strength and dimensional stability of composite materials. In addition, POM can also be modified by chemical or physical methods to improve its wear resistance.
