Key technologies for connecting semi-finished products in both pure thermoplastics and dual laminates are rod welding and extrusion welding. The post-chlorinated polyvinylchloride (CPVC) welding rod is therefore a
n important component for the entire system. Until now, many different CPVC rod qualities have been used, requiring precise specification and control of correct implementation. Together with fabricators GF DEKA and Simona, this company has developed a new welding-rod generation, which was commercialized last month. The new CPVC welding rod is available in diameters of 3 and 4 mm, and offers the following advantages: genuine system behavior with regard to corrosion resistance; compatibility with sheets and pipes; matching and exceeding the performance of state-of-the-art CPVC welding-rod products (for instance, in contact with wet chlorine or anolyte); and more. — Lubrizol Advanced Materials Europe BVBA, Brussels, Belgium
