Polyacetal Plastic Sheet is one of the engineering plastics which also call Polyoxymethylene(Polyformaldehyde) plastic sheet,whichis One of the synthetic resin, also known as polyformaldehyde resin, POM plastic, and steel, etc.It is a kind of white or black plastic granule with high hardness, high steel and high abrasion resistance.Mainly used for gears, bearings, auto parts, machine tools, instruments, etc.
Advantages:
1. Excellent abrasion and creep resistance property;
2. High dimensional and shape stability;
3. Retains toughness under low temperature (-40°C);
4. Resistant to organic solvents; Insoluble under normal temperature;
5. Thermal deformation temperature is close to that of PC, PTFE and nylon;
6. High compressive strength, second only to glass fiber;
7. Good sliding property; wear resistant; non-water absorbent;
Disadvantages:
1. Not resistant to acids, especially to mineral acids;
2. Not resistant to UV;
3. Not self-extinguishing, and thus must be kept away from fire;
4. Not resistant to impact.
Applications:
1. Sliding parts: bearing and lining, roller, conveyor chain;
2. Precision mechanical components: gear, cam, coupler, idler roller;
3. Waterproof components: impeller, pump case, gasket;
4. Electrical parts: guide pulley, spring lock;
5. Fixture, lever, handle, knob and other jig materials.
Production:
1. Pom Plastic Sheet
2. Color : White & Black & Beige & Blue & Other customize
