product overview
POM-C
POM-C is a pure-grade acetal copolymer material. In addition to natural color and black, there are also a series of colors to choose from; POM-C copolyformaldehyde is more resistant to hydrolysis, strong alkali and thermal oxidation than homopolyformaldehyde.
POM-H
POM-H is a homopolyoxymethylene machined profile product. Compared with POM-C, POM-H provides higher mechanical strength, stiffness, hardness and creep resistance, as well as a lower coefficient of thermal expansion and better wear resistance.
Advantage
1.High mechanical strength, rigidity and hardness.
2. Good flexibility.
3. Good creep resistance.
4. Strong impact resistance at low temperature.
5. Excellent dimensional stability (low water absorption).
6. Good sliding and wear resistance.
7. Good machining performance.
8. Good electrical insulation and dielectric properties.
