Plastics. Fluoropolymer dispersions and moulding and extrusion materials. Part 1: Designation system and basis for specifications (ISO 20568-1:2017)

Alkalmazási terület

This document establishes a system of designation for fluoropolymer materials, which may be used as the basis for specifications. The various types of fluoropolymer are differentiated from each other by a classification system based on appropriate levels of the designatory properties and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. For polytetrafluoroethylene (PTFE) For PTFE granular moulding and ram extrusion materials, and for PTFE resin produced from coagulation of dispersion: — standard specific gravity (SSG) — bulk density — particle size For aqueous dispersion of PTFE — PTFE percentage in dispersion — surfactant percentage in dispersion — surfactant tolerance level For melt processable resins For CPT, ECTFE, EFEP, ETFE, FEP, PFA, PVDF, PVF, VDF/CTFE, VDF/HFP, VDF/TFE, VDF/TFE/HFP — melting-peak temperature — melt mass-flow rate For PCTFE — zero-strength time (ZST) For TFE/PDD — glass transition temperature (Tg) For aqueous dispersion of melt processable resins (ETFE, FEP, PFA, PVDF, PVF, VDF/CTFE, VDF/HFP, VDF/TFE, VDF/TFE/HFP) — polymer percentage in dispersion — surfactant percentage in dispersion — surfactant tolerance level The designation system is applicable to all fluoropolymers and blends. It applies to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials and polymer modifiers. 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 may be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20568-2, if suitable. In order to specify a thermoplastic material for a particular specification, the requirements are to be given in data block 5 (see 4.1).
