GB/T 46197.1-2025 Plastics—Polyetheretherketone (PEEK) moulding and extrusion materials—Part 1:Designation system and basis for specifications

Scope

This document establishes a naming system and classification basis for polyetheretherketone (PEEK) molding and extrusion materials. PEEK polymers are polyaryletherketone polymers composed of ether bonds and carbonyl groups sequentially connected to a phenyl ring in the order of etheretherketone. Different types of PEEK plastics are distinguished based on the following specified characteristic performance values and specific applications and/or processing methods, important properties, additives, colorants, fillers, and reinforcing materials: - a) melt viscosity or melt flow rate; - b) tensile modulus; - c) tensile strength. This document applies to all PEEK materials. This document applies to powdered, granular, or crushed materials that are either unmodified or modified with colorants, fillers, reinforcing agents, or other additives. This document does not imply that materials with the same name necessarily have the same performance. This document does not provide engineering data, performance data, or processing condition data required to illustrate the special applications and/or processing methods of the materials. These additional properties can be determined using the test methods specified in GB/T 46197.2 if necessary. To illustrate the special applications of a certain thermoplastic material or to ensure the reproducibility of the processing process, additional requirements are given in Character Group 5 (see 4.1).
