Scope

This document specifies a naming system for ethylene-vinyl acetate (EVAC) copolymer thermoplastic materials, which serves as the basis for classification.
Different types of EVAC plastic materials are distinguished by a classification system based on the values of specified characteristic properties, as well as recommended applications and/or processing methods, important properties, additives, colorants, fillers, and reinforcing materials:
a) Vinyl acetate content;
b) Melt mass flow rate.
This document applies to ethylene and vinyl acetate copolymers with a vinyl acetate content of 3% to 50% (mole fraction approximately 25%). It applies to materials that are typically in powder, granular, or crushed form, unmodified or modified with colorants, additives, fillers, etc.
This document does not imply that materials with the same name must have the same properties. It does not provide the engineering data, performance data, or process parameters required to describe the special applications and/or processing methods of the materials. When necessary, these additional properties should be determined using the test methods specified in GB/T 30924.2.
