POM Material

POM (polyoxymethylene) is a highly crystalline thermoplastic engineering plastic, commonly known as "super steel" or "superior steel". It is synthesized from formaldehyde as a raw material and primarily classified into two types: homopolymethylene (POM-H) and copolymethylene (POM-C)

Homopolyoxymethylene (POM): It has higher density, crystallinity, and melting point, but poorer thermal stability, a narrower processing temperature range (about 10°C), and weaker acid and alkali resistance;

Copolymethylene: It has good thermal stability, a wide processing temperature range (about 50°C), and superior acid and alkali resistance, but its density and strength are slightly lower than those of homopolymethylene.

Excellent mechanical properties

High hardness, high rigidity, and high strength, approaching the specific strength and specific rigidity of metals;

With outstanding wear resistance, self-lubricating properties, and fatigue resistance, coupled with a low friction coefficient, it is suitable for moving parts;

It has good dimensional stability and is less affected by temperature (long-term operating temperature: -40°C to 100°C).

Chemical and electrical properties

Resistant to oil and organic solvents, but poor in resistance to strong acids and alkalis;

It has excellent electrical insulation properties and is not affected by humidity and temperature.

Primarily used for manufacturing mechanical components that require high precision and wear resistance:

Transmission parts: gears, bearings, cams, etc;

Automotive industry: fuel system components, seat belt buckles, etc;

Precision instruments: instrument internals, pipeline fittings, electronic components, etc.
