Why vinyl in polyvinyl fluoride.

Polyvinylidene fluoride or polyvinylidene difluoride pvdf is a highly non reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Find out information about polyvinyl flouride. A plateau was observed at about 2000 ppm 3733 mg cu m suggesting saturation of vinyl fluoride metabolism. Pvf has low permeability for vapors burns very slowly and has excellent resistance to weathering and staining.

The fluoride concentrations in the urine of rats were found to be increased 45 and 90 days after exposure by inhalation to 0 200 2000 or 20 000 ppm 373 3733 or 37 333 mg cu m vinyl fluoride for 6 hr per day five days per week for about 90 days. It is structurally very similar to polyvinyl chloride. The above objects are accomplished by polymerizing vinyl fluoride under the conditions disclosed herein wherein orientable polyvinyl fluoride is formed these conditions involving a pressure of at least 150 atmospheres in the presence 0 of an organic peroxy compound and continuing the reaction under such pressure until a substantial amount of vinyl fluoride has been converted to orientable polyvinyl fluoride. It is also resistant to most chemicals except ketones and esters.

Polyvinyl fluoride pvf a synthetic resin produced by polymerizing vinyl fluoride ch 2 chf under pressure in the presence of catalysts. Used for packaging and electrical. Has superior resistance to weather chemicals oils and stains and has high strength. Explanation of polyvinyl flouride.

Pvdf is a specialty plastic used in applications requiring the highest purity as well as resistance to solvents acids and hydrocarbons. Polyvinyl fluoride is a thermoplastic fluoropolymer with the repeating vinyl fluoride unit. Vinyl fluoride monomer was synthesized directly from acetylene.
