The table in this document summarises the data given in a number of chemical resistance tables at present in use in
various countries, derived from both practical experience and test results.
The table contains an evaluation of the chemical resistance of a number of fluids judged to be either aggressive or not
towards low and high density polyethylene. This evaluation is based on values obtained by immersion of low and high
density polyethylene test specimens in the fluid concerned at 20 and 60°C and atmospheric pressure, followed in
certain cases by the determination of tensile characteristics.
A subsequent classification will be established with respect to a restricted number of fluids deemed to be
technically or commercially more important, using equipment which permits testing under pressure and the
determination of the “coefficient of chemical resistance” for each fluid. These tests will thus furnish more complete
indications on the use of low and high density polyethylene products for the transport of stated fluids, including their use
under pressure.
SCOPE AND FIELD APPLICATION
This document establishes a provisional classification of the chemical resistance of low and high density
polyethylene with respect to about 300 fluids. It is intended to provide general guidelines on the possible
utilisation of low and high density polyethylene: – at temperatures up to 20℃ and 60℃
– in the absence of internal pressure and external mechanical stress
(for example, flexural stresses, stresses due to thrust, rolling loads, etc.).
