Product Description

Injection moulding automotive applications weather resistant pom paraformaldehyde raw material particles

Polyoxymethylene(POM): is also commonly known as (Poly)acetal, POM is a kind of Semi-crystalline Polymers, strong, has nice rigidity, and high mechanical strength, which means it is widely used in different industrial usages. The chemical formula of Polyoxymethylene is (CH2O)n.

 

POM can be divided into homopolymer and copolymer by different manufacturing processes, below please check the comparing properties of them:

• Polyoxymethylene-Homopolymer (POM-H): Also known as Acetal Homopolymer, with higher crystallinity, thus the density, melting temperature, and rigidity are also higher, and the tensile strength is higher as well. POM-H has better mechanical properties, and a shorter molding cycle time, so it can help reduce molding costs and it allows us to use on different mold designs.
• Polyoxymethylene-Copolymer (POM-C): Also known as Acetal Copolymer, which has better resistance to chemical solvents (alkaline environment), it has lower melting temperature, and faster molding cycles, thus it's easier for manufacture processing, furthermore, it has better maintenance of color under UV exposure.

Features: 

1, POM has a very low coefficient of friction and geometric stability, POM plastic is particularly suitable for the production of gears and bearings.
2, POM has high-temperature resistance, so POM is also used in pipeline devices.
3, POM is a tough and elastic material, POM still has good creep resistance even at low temperatures, and POM has good geometric stability and impact resistance.
4, the high degree of crystallization of POM leads to its high shrinkage, POM plastic can reach 2% to 3.5%. POM has different shrinkage rates for a variety of different reinforced materials.
