1Chemical Resistance Chart
Polyethylene & Polypropylene
Polyethylene Pipe and Fittings have excellent resistance to chemical attack. However, where aggressive chemicals are to be conveyed, the
suitability for use should be checked against the chart below.
The chart is intended as a guide only. The actual performance can not be guaranteed as indicated for every case as there are too many
variables.
The chemicals listed are the common base constituents of many products used in the agricultural industry. If the fluid is not listed, reference
should be made to the chemical supplier to ascertain its chemical make-up.
