Scope

This document specifies the naming system and classification basis for polyphenylene ether (PPE) molding and extrusion materials.
Different types of PPE plastics are distinguished based on specified characteristic performance values (load deformation temperature, melt volume flow rate, notched impact strength of a simple beam, flame retardancy grade) and a classification system based on specific applications and/or processing methods, important properties, additives, colorants, fillers, and reinforcing materials.
This document applies to all PPE materials, including those modified with polystyrene or polyamide.
This document applies to powdered, granular, or sheet materials, either unmodified or modified with colorants, additives, fillers, etc.
Materials with the same name in this document do not necessarily have the same performance. This section does not provide the engineering data, performance data, or processing conditions data required for specifying materials. If needed, these additional properties can be determined using the test methods specified in GB/T 45475.2.
To clarify the special applications of a certain PPE thermoplastic material or to ensure the reproducibility of processing, additional requirements can be provided in character group 5 (see 4.1).
