Praedifa Technology Division - Acids and Caustic Solutions

Acids and Caustic Solutions

Chemistry is omnipresent. Not only biological processes, but many other processes in our environment as well, are based on chemical reactions that make human life easier and enhance its quality.


Acids and caustic solutions are used in a wide range of industrial applications. They are starting materials which, due to their reactivity and various concentration levels, should be looked at specifically in terms of the chemical resistance of the materials coming into contact with them. Therefore, the relevant concentration of the acid or caustic solution used in process equipment is a primary aspect to be considered in selecting the appropriate sealing compounds.


Drawing on many years of experience in engineered materials and engineering design, Parker Prädifa supports you in developing, designing and selecting sealing solutions for application with acids and caustic solutions and will always provide you with a suitable solution.
