About POM:
Energetic offers copolymer grade of POM Rod, Sheet. It's a semi-crystalline material with high strength, a low coefficient of friction and good wear properties especially in wet environments (resistance to hydrolysis). Copolymer acetal also offers better chemical resistance than homopolymer acetal.
Advantages:
POM's great machinability together with its impact fatigue and shock resistance, low coefficient friction, and self-lubricating, dimensional stability, mechanical strength, zero moisture absorption, good dielectric properties, solvent resistance, non-stress cracking, no porosity and good load-bearing properties make it ideal for close-tolerance parts.
Key Features:
- High mechanical strength
- Dimensional stability
- Excellent machinability
- Good creep resistance
- Very low stick-slip
- Physiologically inert
- Low moisture absorption
- Continuous use at temperature -50 centi-degrees to +110 centi-degrees
Applications:
- Precision gears, springs, wheels, connecting rod, impeller blades
- Bearings with close tolerance
- Electrical engineering insulations
- Snapfit assemblies
- Automobile industry
- Toys, windows, water tanks and so on.
