Developments in Materials for Pipes # 2001 Munich
The paper examines the production of PVC and its conversion into PVC-U pipes. Advances in chemistry, process engineering and the design of extrusion equipment have led to significant improvements in quality and consistency of both PVC polymers and pipes made from them. At the same time, pipe productivity has risen more than threefold. The contributions made by the improvements in polymer quality and novel pipe designs are examined. Further improvements are discussed as are the credentials of PVC pipes in the emerging discussions concerning the waste management and sustainability issues.
