Good light transmission customized injection POM sheave
Description
POM (Full-name: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised “Plastic Steel”, and has comprehensive excellent performances, such as: wear-resistance, high hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability. POM has widely applied in Automobile industries, electronic and electric products, commodity, pipeline & fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and EPT metals.
Characteristic
1. EPT impact resistance.
2. Continuous working temperature :-40 ~120°C’ .
3.Good light transmission
4.Good weather resistance and UV protection
5.High heat insulation
6.Simply processed and installed
7.UV protection layer: 50um
8.Soften temperature :148°C
