POM sheet Features:

POM sheet (and rod) has the following characteristics: Outstanding wear resistance, Low coefficient of friction, Outstanding chemical resistance, Excellent mechanical properties (i.e. strength & stiffness) Good temperature resistance. POM material is used in many static & dynamic industrial applications replacing materials like; steel brass, bronze, copper and aluminium. It have improved part life because of better wear, more chemical and corrosion resistance. These materials reduce factory noise and will reduce or eliminate the need for lubricants.

POM sheet 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 sheet 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 sheet Application:

POM material can be used in applications such as; Gears, Bushings, Bearings, Rollers, Timing Screws, manifolds, Valves and Valve Bodies, Washers, Wear Pads, and many industrial machine parts
