Scope

This part of GB/T 22271 specifies a naming system for the classification of polyformaldehyde (POM) thermoplastic materials. Polyformaldehyde is a thermoplastic material composed of long-chain homopolymers and copolymers synthesized from formaldehyde. The main chain of the polymer is formed by the polymerization of formaldehyde, and its main repeating unit is —CH2O—.
