Subject of the standard: | This document establishes a system of designation for polyoxymethylene (POM) thermoplastic material, which can be used as the basis for specifications. NOTE Polyoxymethylene materials are thermoplastic materials composed principally of long-chain synthetic homopolymers and copolymers of formaldehyde. The repeating unit in the molecular chain is ? CH2O ? as an integral part of the main polymer chain resulting from polymerization of formaldehyde. The types of polyoxymethylene plastic are differentiated from each other by a classification system based on appropriate levels of the following designatory properties: a) melt mass-flow rate or melt volume-flow rate; b) tensile modulus, and on information about basic polymer parameters, intended application, method of processing, important properties, additives, colorants, fillers and reinforcing materials. |
