- What is ISO 21304-1- PE – UHMW moulding and extrusion materials about? ISO 21304-1 establishes a system of designation for thermoplastic PE-UHMW materials, which can be used as the basis for specifications. The types of PE-UHMW are differentiated from each other by a classification system based on appropriate levels of the designatory properties: Viscosity number Elongational stress Charpy double-notched impact strength NOTE 1: This designation system is applicable to all PE-UHMW homopolymers and to ultra-high-molecular-weight copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 % by mass and a content of non-olefinic monomers with functional groups up to a maximum of 3 % by mass. It applies to materials ready...
