POM C Sheet Rod Bush Parts Machining Components

It is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. Polyoxymethylene Co polymer (POM-C) is also known as Acetal and Polyacetal. It is produced by different chemical firms with slightly different formulas.

The principal applications are in high performance engineering components such as ski bindings, fasteners, knife handles, lock systems, small gear wheels, ball bearings and model rocket launch buttons. It is extensively used in the consumer electronics and automotive industry.

Commonly extruded as continuous lengths of round or rectangular section; POM-C can be cut to length and sold as bar or sheet stock for machining.

POM-C Machining
POM-C may be machined using traditional methods such as turning, milling, drilling etc. when supplied as extruded bar or sheet.  Where production economics do not merit the expense of melt processing, these processes are employed. The material is easy to cut and requires sharp tools with a high clearance angle. It is recommended to use soluble cutting lubricant, although not necessary.

POM-C Properties

• Chemical resistance to fuels and solvents
• Very Good dimensional stability
• High creep resistance
• Good Electrical and Die electrical properties
• High Heat resistance
• High abrasion resistance
• Good machinability
• Good wear resistance and sliding properties
• High mechanical strength, stiffness and toughness

POM-C Field Of Application
For components with particularly high requirements in terms of dimensional stability and visual effect.

POM-C Mechanical engineering, automotive industry, manufacture of chemical equipment
E.g. meter components, sliding elements, gears, control discs, impellers, bearings, pump components, valve bodies, catch elements, coil bodies, bearing cages, clutch parts, pump housings
