Over past decades there has been a shift from the original systems used in the semiconductor high-purity water processing industry which were made of steel pipes with high metal ionic extractables to plastic piping which brought further concerns such as total organic carbon contamination to the use of polyvinylidene fluoride (PVDF). Data showed that PVDF was naturally stable and maintained its properties for a sufficient length of time. This article elaborates on the design of PVDF and its properties making it an efficient alternative to traditional piping systems as well as discussing end-users of PVDF in pure water and new applications for PVDF.
