POM (polyoxymethylene or acetal) is a thermoplastic which belongs to the family of polyacetals. This is available in two forms: Homopolymer (POM-H) and Copolymer (POM-C). POM-H benefits from mechanical properties but less resistance to UV rays, while POM-C has better chemical and thermal properties. This material is characterized by very high impact resistance, while maintaining good flexibility, high tensile and breaking strength, as well as good electrical insulation.
