Chemical compatibility, chemical resistance and corrosion resistance are among the greatest advantages of plastics in comparision to metals. By choosing the right polymer family, the user can put himself in the position of being able to withstand even the harshest environmental conditions without the need for additional protection such as surface treatment, painting or cathodic protection. In our product portfolio you will find specific acid resistant plastic materials, polymers resistant to strongly alkaline media, including hot water and steam, as well as solvent resistant plastics. Users will also find they are able to choose a balanced chemical resistant plastic suitable for a variety of end uses.
The following tables give an indication of pH limits and substance categories to be used as a general guide to plastic chemical resistance, and to indicate where different product families may be used, under room temperature conditions with no mechanical load.
