Materials

In tank production we use only materials of highest quality standards, which will be carefully selected according to customer needs, for example by chemical resistance for transported goods. Materials are easy to maintain and clean.

Chemical Resistance

The chemical resistance table shows the corrosion behaviour of the 3 inner lining materials. GRP(glassfibre reinforced plastic) with vinylester resin already gives wide resistance against chemicals If moderate corrosion and temperature resistance is needed the polyethene lining gives a very cost effective alternative. For more requiring applications we can offer Halar (E-CTFE) inner lining, which can resist practically all chemicals transported by road.
