Specific Material Description

PVC-C is a post-chlorinated polyvinyl chloride which, compared with PVC-U, has an improved chemical resistance and abetter stability at high temperatures. In addition, the good weldability and glueability of the material offer extensive constructive opportunities. The continuously permissible use temperature of PVC-C is 90 ° C with the possibility of short-term temperature peaks up to 95 ° C.
