POM Rod Features:

a general engineering thermoplastics with excellent mechanic properties,eletrical properties,wear resistanance,dimensional stability,chemical corroosion,in particular,are resistant to fatigue-type attack,and good self-lubricating,are latent behalf of the matal,especiallly coper and aluminnum, zinc and other non-ferrous metals and alloys ideal for engineering plastics manufacture.

POM rod Advantages:

1)No microporosity.

2)High strength

3)High rigidity

4)High thermal stability

5)Good electrical insulation properties

6)Very good sliding properties

7)High resistance to solvents

8)Very high resistance to stress cracks

 POM rod Disadvantages:

POM by acid erosion, weathering poor, poor adhesion, thermal decomposition and softening nearly stable, so melting process more difficult. Limiting oxygen index for the smallest plastic, it is easier to burn.

POM rod Application:

Because POM  has excellent chemical resistance and very low moisture absorption, it is often chosen and is a widely specified engineering plastic within the brewing industry. Also because of the very low moisture absorption, POM sheet is highly recommended within the food industry having received Food & Drug Administration approval and also the marine industry for the fact that POM sheet is non hydroscopic the finished machined product will not expand or swell due to moisture absorption.
