Plastics pipes and fittings for industrial applications — Collection of data on combined chemical-resistance

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.
