TECAFLON® PVDF Plate

TECAFLON® PVDF is unfilled polyvinylidene fluoride, a semi-crystalline fluoropolymer in machinable rod and plate. Unlike PTFE it carries real mechanical load: tensile strength about 7,800 psi at break (7,250 psi at yield), modulus of elasticity near 350,000 psi and roughly 35% elongation at break, with far better creep resistance and machinability than PTFE at comparable chemical performance. Continuous service temperature is 300°F and the melting point is 342°F. Water absorption is about 0.02%, it is inherently flame retardant at UL94 V-0, and it resists acids, hydrolysis, UV and weathering without added stabilisers, which keeps high-purity fluid streams clean.

It is a standard material for wetted parts in aggressive chemistry: pump housings and impellers, valve bodies and seats, fittings, nozzles, tank and duct linings, filter plates, column internals and semiconductor wet-bench and high-purity fluid handling components, plus cleanroom, medical and food processing hardware. The material is FDA compliant and meets EU Regulation 10/2011 for food contact. It machines cleanly with sharp tooling and light cuts, and it can be thermally welded, which makes fabricated assemblies practical. Strong bases, amines and polar solvents such as ketones and esters are the recognised exceptions to its chemical resistance, so verify compatibility before committing a part.
