Le POM présente une excellente résistance aux solvants organiques, huiles, graisses et carburants. Sensible aux acides forts et bases concentrées (hydrolyse). Incompatible avec les oxydants forts. Bonne tenue en milieu humide et dans l'eau chaude.

Frequently asked questions
Injection moulding at 185–215 °C, mould temperature 80–100 °C. Highly susceptible to thermal degradation (release of formaldehyde above 230 °C). High shrinkage (1.8–2.5 %) → appropriate mould design is essential. No pre-drying required if stored correctly.
POM is a recyclable thermoplastic. Recycling is limited by its sensitivity to thermal degradation. Depolymerisation allows for the recovery of formaldehyde. Recycled grades exist for non-critical applications.
POM-FDA grades are approved for food contact (cold and hot water). Used in taps and kitchen equipment. Check the specific grade with the supplier.
