Chemical Resistance

 

Acrycast generally has a good resistance to water, alkaline agents, aqueous solutions of inorganic matter and even some diluted acids. Acrycast will absorb small amounts of water – this is not an issue unless you are then heating and forming the product as the quick release of the moisture can cause blistering. It is important that you store Acrycast according to the specified conditions (see general information section).

Please find below a table showing a list of chemicals that Acrycast has been tested against – clearly these tests have been done in the laboratory in controlled conditions and any minor variation can cause a change in the results. Therefore to ensure compatibility please test the products prior to production.

Key

0 = Not resistant – it dissolves, attacks, damaged the Acrycast so it loses its strength, clarity etc.

5 = Partial Resistance – there might be some slight staining, crazing or some swelling of the Acrycast. It will however retain its integral strength.

10 = Resistant – after sustained contact there may be a minimal amount of staining on the surface of the Acrycast.
