Polyvinylidene fluoride (PVDF) has long been used for industrial monofilament applications. In this article for Filtration+Separation Sean M Stabler, James Henry, and Jerome Chauveau of Arkema, developers of the new Kynar PVDF, discuss how fresh grades allow the dimensions of fibres to be scaled down to very low diameter fibres, giving access to new opportunities. They state it is an adaptable fluoropolymer, whioh can be applied to many markets including transportation and chemical processing.
