Angol cím

Plastics. Unplasticized poly(vinyl chloride) (PVC-U) moulding and extrusion materials. Part 1: Designation system and basis for specifications (ISO 21306-1:2019)

Alkalmazási terület

This document establishes a system of designation for unplasticized PVC thermoplastic material which may be used as the basis for specifications. The types of PVC-U plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) Vicat softening temperature, b) impact strength (Charpy notched), c) modulus of elasticity and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This document is applicable to all unplasticized compositions of homopolymers and copolymers that contain at least a mass fraction of 50 % of vinyl chloride. It is also applicable to compositions containing chlorinated poly(vinyl chloride) and to compositions containing blends of one or more of the above-mentioned polymers, provided that the total amount of these polymers represents at least a mass fraction of 50 % of the polymer content of the composition. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. This document does not apply to cellular plastics. It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they can be determined in accordance with the test methods specified in ISO 21306-2, if suitable. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 4.1).
