Introduction

Polyetheretherketone (PEEK) is a high-performance engineering plastic with excellent properties, including high heat resistance, radiation resistance, corrosion resistance, and dimensional stability.

It exhibits good stability, excellent electrical properties, and superior processing performance. Polyetheretherketone (PEEK) possesses advantages in relevant applications that other polymers cannot match.

Its superior performance makes it one of the most high-performance specialty engineering plastics. The demand for polyetheretherketone (PEEK) materials has grown rapidly in recent years.

It is widely used in defense, aerospace, electronics and information, petrochemicals, medical and health, home appliances, automobile manufacturing and other fields, and plays a significant role in these fields.

Important role.

Currently, my country has not yet formulated relevant national standards for polyetheretherketone (PEEK) molding and extrusion materials. To promote the application of PEEK products...

To support the application and evaluation of polyetheretherketone (PEEK) plastics, GB/T 46197 "Plastics - Polyetheretherketone (PEEK) Molding and Extrusion" was developed.

Material".

GB/T 46197 "Plastic Polyetheretherketone (PEEK) Molding and Extrusion Materials" is proposed to be divided into two parts.

---Part 1: Nomenclature System and Classification Basis. The aim is to establish a nomenclature system applicable to polyetheretherketone (PEEK) molding and extrusion materials.

Naming conventions and classification principles distinguish different types of polyether ether ketone (PEEK) molding and extrusion materials.

---Part 2: Sample Preparation and Performance Testing. The aim is to establish suitable materials for molding and extrusion of polyetheretherketone (PEEK).

Sample preparation, sample conditioning, and test conditions.
