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                                                              PE NOTE 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-U Polyvinyl chloride, chlorinated                             PVC-C Polybutylene                                                              PB Acrylonitrile/butadiene/styrene                         ABS Polyvinylidene fluoride                                          PVDF NOTE 2        This document considers homopolymer PVDF. Cross-linked polyethylene                                     PE-X (PE-Xa, PE-Xb, PE-Xc) Ethylene chloro trifluoro ethylene                       ECTFE Polyamide, 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                                                                PSU Perfluoralkoxy                                                          PFA NOTE 4        Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer. Polytetrafluoroethylene                                         PTFE NOTE 5        Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer.     Polyphenylene sulphide                                          PPS NOTE 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.
