From wikipedia the free encyclopedia polyvinyl fluoride pvf or ch 2 chf n is a polymer material mainly used in the flammability lowering coatings of airplane interiors and photovoltaic module backsheets. It is also used in raincoats and metal sheeting. From wikipedia the free encyclopedia polyvinylidene fluoride or polyvinylidene difluoride pvdf is a highly non reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Polyvinyl fluoride pvf a synthetic resin produced by polymerizing vinyl fluoride ch 2 chf under pressure in the presence of catalysts.

Fluoride appears to be a metabolite of vinyl fluoride as it is found in the urine six days after exposure. Polyvinyl fluoride and polyvinyl chloride see more. It is structurally very similar to polyvinyl chloride. Polyvinyl fluoride is a thermoplastic fluoropolymer with the repeating vinyl fluoride unit.

Since that time it has established itself as a polymer with excellent resistance to sunlight degradation uv resistance thermal stability chemical attack water absorption and solvents. Developed as a coating its first widespread commercial use was as a pigmented liquid coating called kynar 500. Today pvdf is used as a coating for metals. Polyvinyl fluoride and polytetrafluoroethylene see more polyvinyl chloride.

Polyvinyl fluoride pvf or ch 2 chf n is a polymer material mainly used in the flammability lowering coatings of airplane interiors and photovoltaic module backsheets. Pvdf is a specialty plastic used in applications requiring the highest purity as well as resistance to solvents acids and hydrocarbons. 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. The commercial pvf film tedlar was first trademarked by dupont 50 years ago.

It is also used in raincoats and metal sheeting. Polyvinyl fluoride pvf or ch 2 chf n is a polymer material mainly used in the flammability lowering coatings of airplane interiors and photovoltaic module backsheets. I it is also used in raincoats and metal sheeting. Polyvinyl chloride also known as polyvinyl or vinyl commonly abbreviated pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene.
