Classification System and Basis for Specification for Polyphenylene Ether (PPE) Materials
2016
7
ASTM Vol.08.02 (2022)
This classification system covers the basic polymers and copolymers known as polyphenylene ethers and polyphenylene oxides, as well as filled, modified, and reinforced versions. Recycled materials are included in this standard as Class 5 of Table PPE. NOTE 1: The addition to the natural polymer or copolymer of pigments, colorants, or other additives can cause the final composition to no longer meet the requirements specified for the natural polymer or copolymer. NOTE 2: The preferred abbreviation for polyphenylene ether is PPE, as noted in Terminology D1600. This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the plastic field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this standard.
