Pvf Raw Material Resin Polyvinyl Alcohol Resin Chinese Supplier

PVF plastic particle properties --PVF has general fluorine resin common weather resistance, chemical resistance and non-viscosity, mechanical strength is larger, has excellent performance and insulation. The PVF film produced by the United States Du Pont company's trademark is Tedlar, transparent and colored two; And according to the different molecular orientation into five types of film: type I for unsaturated polyester glass fiber reinforced plastic release; Type II is a high strength and high modulus film; Type III is a universal membrane. Type iv is high elongation and high tensile strength film; Type V is a special film, suitable for the complex shape of aircraft internal components used. The main applications of PVF resins are thin films and emulsion coatings. PVF film has high mechanical strength in fluorine plastics, continuous use temperature of -70 ~ 150ºC, PVF film has high dielectric constant and high breakdown voltage value, and has excellent hydrolysis resistance and aging resistance, which makes it an important electrical and electronic material, widely used in the protective material of solar cells, PVF hydrolysis resistance is good, The strength is not affected by water vapor for 1500h, and the elongation and impact strength only decrease slightly. In 10% (mass fraction) hydrochloric acid and sodium hydroxide aqueous solution in 60ºC for 7 days, the appearance did not change; Resistant to aliphatic hydrocarbons, aromatics and alcohols, insoluble in solvents below 100ºC, can be dissolved in polar solvents above 100ºC.
 

(1) Protective layer of building materials PVF film as a protective layer of outdoor and indoor building materials, due to its weather resistance, low maintenance costs and attention. PVF thin-film laminated plywood wall coverings, indoor light diffuser panels, asbestos cement laminates and glass fiber reinforced polyester panels have been used as building materials. Pla-tal-T film laminated steel can be applied to industrial and civil building walls, ceilings, shops, car parking and waiting room exterior wall protection. Because the surface of the film is not easy to be contaminated, even after being contaminated it is easy to wash, so it is especially suitable for hospitals, food processing plants and public places of walls and doors and Windows of the protective layer, Japan Kanto leather company Tedlar film laminated on PVC film, used as wallpaper, this wallpaper has a long service life, the surface will not be parasitic mold, Applicable to hotels, restaurants, hospitals, schools, institutions and other departments. As the finishing progress of the interior panel of aircraft cabin, Tedlar film has been adopted in the finishing of the interior panel of Boeing 747. (2) horticultural greenhouse material PVF film has the best weather resistance, low temperature resistance and light transmission, is an ideal greenhouse material. As a greenhouse film, the use cycle can be as long as 8 years, much more than polyester film and polyethylene film. Glass fiber reinforced polyester board is commonly used as greenhouse material, but its weather resistance is poor. The polyester board laminated with PVF film can retain 95% of the original transparency after 5 years and 80% after 10 years. Plates without film protection turn yellow quickly in sunlight and retain only 55 percent of their original clarity after six years of use. In general, with PVF film, the life of reinforced polyester board can be extended 3-6 times. Currently, air-inflatable greenhouses made of PVC film are also covered with Tedlar, 0.012mm thick.
