polyoxymethylene (POM)

It is a crystalline thermoplastic plastic with an obvious melting point of 165~175°C, and its properties are closest to metals. It is generally called plastic steel.

Advantage:

1. It has high mechanical strength, rigidity, environmental resistance, and repeated impact;

2. It has good dimensional stability, elasticity, self-lubrication and wear resistance;

3. Good temperature resistance (-40℃~120℃), good dielectric and organic solvent resistance.

Disadvantages:

1. Easy to thermally decompose under high temperature for a long time;

2. No self-extinguishing, poor acid resistance;

3. Large forming shrinkage.

Use:

Electronic appliances: washing machine, juicer parts, timer components;

Automobile: handlebar parts, power window parts;

Industrial parts: mechanical parts, gears, handles, toys, screws.
