Kynar® PVDF bags are manufactured from an ultra-clean top-grade 3-mil Kynar® PVDF (polyvinylidene fluoride [PVDF]). This material offers excellent corrosion and chemical resistance at both ambient and elevated temperatures. The Kynar® PVDF sample bags are delivered with polypropylene, PTFE and stainless steel fittings.
FluoroMark™ TW 08 films, based on Kynar® PVDF technology, are high-performance fluoropolymer films with uses in several markets and applications including solar panel topsheet and backsheet, gas-sampling bags, oil and gas storage liners, anti-graffiti coverings, and applications requiring extreme weathering resistance. FluoroMark™ films are offered at several thicknesses as well as glossy or matte finish to meet your product needs. Kynar® is a registered trademark of Arkema.
