Chemical Resistance Chart

Click the icon below to download our Chemical Resistance Chart (9.5MB).

Redeveloped for 2017, our extensive chemical resistance chart, for now, features 10 different polymers rated from ‘Good’ to ‘Poor’ against more than 600 chemicals and substances, at different temperatures. We hope this useful tool helps you find the right material for your application.

Resistance ratings for ten primary materials used in the manufacture of our products, against a wide range of chemicals and mixtures. The symbols used to denote performance are as follows:

  • Good Resistance
  • Fair Resistance
  • Limited Resistance
  • Poor Resistance
 

In order to give guidance, the resistance of PVC to some chemicals has been predicted from its resistance to other chemicals which have a similar composition. Such predictions are shown using an asterisk (*) with the symbols listed above.

It may be safely assumed that chemical resistance decreases with both increasing temperature and with increasing concentration of reagent, and that the reverse is also true. No valid assumptions can be made, however, if the temperature and concentration move in compensating directions.

Chemical resistance of polyurethane hoses and composite hoses sleeved with polyurethane. The polyurethane is not recommended for continuous use in contact with water above 40°C (or solutions containing water above 40°c) because of its hydrolising effect. Hydrolysis can also occur with long exposure to:

  • high humidity at elevated temperatures
  • acid and alkali solutions
  • aerated water
  • fungi and bacteria
 

Some substances having a satisfactory rating may give swelling but this is usually minimal. The assumption should not be made that this indicates deterioration of the polyurethane.
