GB/T 21461.1-2023 focuses on plastic ultra-high molecular weight polyethylene (PE) (PE-UHMW) molding and extrusion materials. It establishes a naming system to clarify the basis for classification according to material characteristics. It stipulates that materials are named by key performance indicators such as density, melt mass flow rate, etc., and different types of PE-UHMW materials are given precise identification. The standard unifies the industry's understanding and communication of materials, helps production and processing enterprises to accurately select materials, promotes the rational application of PE-UHMW in many fields, and lays a solid foundation for the subsequent formulation of relevant product standards.
