PVDF
Polyvinylidene fluoride
PVDF, also known under the brand name Kynar, is a fluoroplastic with excellent chemical resistance, high purity and good mechanical strength. The material is stronger and stiffer than PTFE and FEP, and can be welded with hot air and IR welding. PVDF is widely used in the chemical process industry and the semiconductor industry, where high purity and chemical resistance are crucial. The material is inherently flame retardant and has good UV resistance. We have PVDF in plates, round rods, tubes and weldable profiles.
