With Polystone® P flex grau we now offer a material which is flexible, weldable and provides a good resistance to many chemicals. The material can also be welded to Polystone® P solid sheets. This gives a whole new range of options when it comes to chemical tank and plant construction.

With the new formulation we have managed to improve the weldability of Polystone® P flex to Polystone® P solid sheets. We look forward to new applications with our customers.
