The following table shows the most common insulation and sheathing materials used by SAB Bröckskes for the production of electrical cables. Other materials can be offered on customer request.
In the table you can see different insulation materials or sheath materials, the designation and the most important properties such as temperature resistance, flame resistance, tensile strength, elongation at break, abrasion behavior, dielectric constant, specific resistance, breakdown voltage and radiation resistance.
Chemical resistance characteristics of insulation and sheathing materials can be found here.
