What are the advantages and disadvantages of POM plastics?

1. The advantages of POM, a thermoplastic plastic:

1. The tensile strength is higher than that of ordinary nylon, and it is fatigue-resistant and creep-resistant

2. The dimensional stability is good;

3. The water absorption is smaller than that of nylon;

4. Good dielectric property;

5. It can be used normally at 12℃;

6. Low friction coefficient;

7. Excellent elasticity, similar to spring action.

Second, the disadvantages of polyoxymethylene POM, a thermoplastic:

1. No self-extinguishing property

2. molding shrinkage is large.

third, the application of thermoplastic POM plastic: wear-resistant transmission stress parts and friction-reducing self-lubricating parts, various gears, bearings, bushings, cages, automobiles, agricultural machinery, plumbing parts, etc.
