This document collects available data on combined chemical resistance of thermoplastic materials typically used to manufacture piping components for industrial applications, against fluids over a range of temperatures.The base thermoplastic materials covered by this classification are:Polyethylene PENOTE 1 The PE considered in this document corresponds to PE-HD, with a minimum density value of 0,935 g/cm3 (e.g.: PE63, PE80, PE100, PE100-RC, PE-RT).Polypropylene PP (PP-R and PP-RCT, PP-H, PP-B)Polyvinyl chloride, unplasticized PVC-UPolyvinyl chloride, chlorinated PVC-CPolybutylene PBAcrylonitrile/butadiene/styrene ABSPolyvinylidene fluoride PVDFNOTE 2 This document considers homopolymer PVDF.Cross-linked polyethylene PE-X (PE-Xa, PE-Xb, PE-Xc)Ethylene chloro trifluoro ethylene ECTFEPolyamide, unplasticized PA-U (PA-U11, PA-U12)NOTE 3 This document focuses on PA-U11 and PA-U12 only, as these long chained PA-U are standardized according to ISO 16486-1; short chained (e.g. PA 66) and plasticized PAs are not used for monolithic plastic piping components.Polysulfone PSUPerfluoralkoxy PFANOTE 4 Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer.Polytetrafluoroethylene PTFENOTE 5 Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer. Polyphenylene sulphide PPSNOTE 6 PPS is new with regards to industrial application and chemical resistance issues; for this reason, manufacturers and end-users are advised to assess the chemical suitability of the material.
