GB/T 41758.2 - 2022 for polyketone (PK) molding and extrusion materials. In terms of sample prepative, the processing method of PK raw materials is specified in detail, as well as key parameters such as temperature and pressure during injection molding and extrusion molding to ensure the sample mass. The performance measurement covers mechanical properties such as tensile strength and Impact strength, as well as thermal performance such as thermal deformation temperature, and clarifies various test methods, instruments and operating procedures. Through this standard, the performance of PK materials can be accurately determined, providing a key basis for its quality control, Product Research & Development, and assisting the promotion and application of polyketone materials in industry, manufacturing and other fields.
