Lamcorr offers extruded PVDF as standard sheets and in fabric-backed rolls and sheets in both copolymer Kynar® 2850 (flex) and homopolymer 740 resins. Like ECTFE, PVDF provides a cost effective solution for mid-range service temperatures. Copolymer sees more frequent use in applications that require flexibility and thermoforming. Homopolymer provides more structural integrity and permeation resistance. Both PVDF grades, though versatile in corrosion protection, do not lend themselves to strong alkaline environments.
