Global PVC Stabiliser Trends for Pipes – Challenges and Practical Experience

 

Dr. Udo Anders

Papers # 2012 Barcelona

PVC is a well-established material, globally utilised, in many different applications, such as window profiles, technical profiles, cables and sheets. In Pipes, PVC is used in pressurised potable water applications, as well as sewerage systems, gas piping systems, gutters and fittings. A Global analysis of PVC stabiliser systems in use, for pipe applications, indicated that except North America, where almost exclusively Sn-based stabilisers are used, Pb-based stabilisers have been the dominating system for the past several decades. During recent years, Ca-based stabilisers have been utilised in many regions. In Europe this has now become the most utilised system. The path to where we have arrived involved significant challenges, and it is fair to say that new obstacles appear as the change becomes more advanced. This presentation aims to give an overview of the story so far, recounting practical experience to highlight the challenges seen.
