Abstract
The invention relates to a tough, flexible multi-layer tube or other structure having a vinylidene fluoride contact layer. Such a tube is especially useful for high-purity contact applications, and contact where chemical resistance is needed. The vinylidene fluoride layer is melt-processible and may be a homopolymer, copolymer or terpolymer.
