Introduction

Polyphenylene ether is an indispensable key material in photovoltaic, electric vehicles, water treatment, high-frequency communication and other industries. It has the advantages of good performance, low water absorption, good high temperature resistance, good electrical insulation and low density, and is widely used in electric vehicle power battery support materials and shells. Materials, photovoltaic cell backplane materials and water treatment materials. At present, there is no applicable national standard for polyphenylene ether molding and extrusion materials in my country, which has brought difficulties to the promotion and application of polyphenylene ether and its domestic and foreign trade. This has brought inconvenience to trade and technical exchanges, affecting the healthy development of the polyphenylene ether industry. Therefore, GB/T 45475 "Plastic Polyphenylene Ether" was formulated. (PPE) molding and extrusion materials". GB/T 45475 is the classification and naming, sample preparation and performance determination of polyphenylene ether molding and extrusion materials. The basic standard provides support for polyphenylene ether product standards. GB/T 45475 "Plastic polyphenylene ether (PPE) molding and extrusion materials" is planned to be divided into two parts. --- Part 1.Naming system and basis for classification. The purpose is to establish a naming system and basis for polyphenylene ether (PPE) molding and extrusion materials Classification. --- Part 2.Preparation of test specimens and determination of properties. The purpose is to provide a naming system and classification system for polyphenylene ether (PPE) molding and extrusion materials. This class establishes rules for specimen preparation, specimen conditioning and test conditions. Plastic polyphenylene ether (PPE) molding and extrusion materials Part 2.Sample preparation and property determination

1 Scope

This document specifies the specimen preparation and test methods for testing the properties of polyphenylene ether molding and extrusion materials. Requirements for conditioning of test materials prior to processing and/or molding and of test specimens prior to testing. The method and conditions for sample preparation are described, and the method for testing the properties of sample materials is given. Suitable and necessary polyphenylene ethers are listed. Properties and test methods of molding and extrusion materials. The performance test methods are selected from the general test methods in GB/T 19467.1.This document also lists a wide range of Other test methods that are applicable or have special significance, and the determination methods of characteristic properties in GB/T 45475.1. In order to ensure the reproducibility and repeatability of the test results, it is necessary to use the sample preparation and condition adjustment methods specified in this document. The test data obtained using specimens prepared under different conditions or using specimens of different sizes may Can be inconsistent.
