CF grades require slightly higher temperatures and pressures. Very abrasive → carbide tooling is mandatory. Almost isotropic shrinkage is very low. Electrical conductivity must be taken into account in the design of parts.
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.
