high precision POM/Derlin roller

POM  Descriptions:

POM is a kind of engineering plastic with good mechanical properties. POM together with UHMW PE,Nylon,PTFE are known as four abrasion resistant plastics.It has almost the same rigidity as metal, so it’s an ideal replacement material of copper, cast zinc, steel, aluminum and other metal materials

POM  Characteristics:

Advantages

1,high surface hardness

2,good wear resistance

3,nice self-lubricating properties

4,good dimensional stability

5,low water absorption

6,oil resistant

7,work under the temperature of  -40-100°C

Disadvantages

1,poor acid resistance

2,not resistant to strong alkali and UV

3,poor notch impact resistace

POM  Applications:

1,Industrial area: used to make gears ,bearings

2,Automobile industry

3,Electronic and electrical appliances

4,Sports equipments
