PVF transparent anticorrosive Flame retardant membrane
PVF film , also known as polyvinyl fluoride film (polyvinyl fluoride), referred to PVF. And a thermoplastic resin . Odorless, non-toxic white powder. Density 1.38. 240 °C above decomposition . Has a crystal structure, high transparency ( via UV ) ,
high electrical insulation properties, high toughness , good chemical resistance , anti-aging and resistance to corrosion.And the ability -73 ~ +121 °C. Molecular fluorine and fluorocarbon copolymer extruded . Or copolymers of fluorine-containing fluorocarbon , greater than any polymer chemical bonding and structural stability. PVF film on the sunshine, chemical solvents, acid corrosion , moisture and oxidation resistance and durability is improved significantly . Film can be used as agricultural film, protective film material , packing grease and corrosive substances, can be used as electrical insulation materials.
PVF film wear resistance , anti- moisture penetration capability and scalability which can be increased to double.
PVF film does not contain plasticizers, color lasting stability, anti- bleaching agent, to prevent chalking and fungal growth . Repulsion of its large surface to prevent dust defiled , easy cleaning and maintenance .
Moreover , not only is the strongest detergent PVF film is not damaged .
From minus 70℃ to 110℃ , PVF film can guarantee excellent performance, the highest peak instantaneous temperature to 200 degrees and will not damage them . Also , PVF film without plasticizer , so it has excellent anti-aging properties and in a very wide temperature range to maintain the toughness and bending. For testing institutions for PVF films for 20 years outdoor weathering tests.
Main Features :
Excellent anti-aging performance
