Acetal Polyoxymethylene � POM

Properties of Acetal Polyoxymethylene –

Polymer Type
Thermoplastic

Advantages
Highly crystalline, more creep resistant than Nylon. Excellent abrasion resistance. Good resistance to solvents (except phenols).Low smoke emission. High gloss surfaces. Lower moisture absorption than Nylons.

Disadvantages
Poor resistance to acids/alkalies (particularly homoploymer). Burns easily, (not available with flame retardants).Limited processing temperature range. Poor UV resistance. High mould shrinkage.

Applications
Gears, bearings, conveyor belt tracks, plumbing fittings, fan blades, pen cases, lock mechanisms, aerosol valves. Spring levers, nuts, screws, video/audio cassette components, disposable lighters, switches
