Chemical Resistance of Insulation- & Sheath Materials for Cables and Wires

SAB Bröckskes uses different insulation and sheath materials for the production of electrical cables and wires. Chemical resistance to certain substances is often required. Chemically resistant cables are often used, for example, in industrial painting plants, water treatment plants, in the chemical industry and in areas where various solvents are used.

Depending on the chemical resistance requirements and the application area of the cables, the following materials are used in modified variants: PVC, SABIX®, PUR, PE, Besilen® (silicone), FEP, PFA and ETFE. At the customer's request, we also use materials other than those mentioned.

The following table shows which insulation and sheathing materials are resistant to certain chemical substances that can often be found in industrial applications:

This information is the result of our many years of experience and has been compiled to the best of our knowledge. However, we would like to point out that they are not binding and a final assessment can only be made under normal working conditions.

–    = poor resistance
o    = average resistance
+   = good resistance
n.v. = not existing
