PVDF piping specifications and performance characteristics approve PVDF pipe up to {{convert|248|°F|°C}} under pressurized system conditions. The pipe does not support fungus growth according to military test standard method 508, 81-0B. Dissimilar from other common thermoplastic pipes, (uPVC, CPVC, PE, PP), PVDF does not exhibit sensitivity to UV light or ozone oxidative damage, approving it for long term outdoor uses.<ref>{{Cite web|url=https://pvcpipesupplies.com/media/documents/kynar_specs.pdf|title=PVDF Performance Characteristics & Data|website=Arkema}}</ref>

Line 115:

One variant called OPVC, or PVCO, represents an important landmark in the history of plastic pipe technology. This molecular-oriented bi-axial high performance version combines higher strength with extra impact resistance.

A ductile variant is the MPVC, polyvinyl chloride modified with acrylics or chlorinated PE. This more ductile material with high fracture resistance is used in higher-demand applications where resistance against cracking and stress corrosion is important. In several studies the long track record of uPVC pipes has been investigated. Recent investigations at the German KRV and the Dutch TNO have confirmed that uPVC water pressure pipes, when installed correctly have a useful life span of over 100 years.<ref name=":0">{{Cite web |last=POLYHOSEurl uPVC Pipes |title=uPVC plumbing systems |url=httpshttp://www.polyhosepipesteppfa.comeu/upvcfast-pipesguide-to-materials/|title = Fast guide to materials|last = TEPPFA, The European Plastic Pipes and Fittings Association}}</ref>
