PVF Film

PVF film, also known as polyvinyl fluoride film (PVF), is a thermoplastic high strength resin. Odorless, non-toxic white powder. The density of 1.38. Decomposition above 240℃. It has crystal structure, high transparency (can pass through ultraviolet), high electrical insulation performance, high tenacity, excellent chemical resistance, aging resistance and corrosion resistance. And can withstand -73~+121℃. Formed by extrusion of a copolymer of fluorine and fluorocarbon molecules. It is a copolymer containing fluorine or fluorocarbon, having greater chemical binding strength and structural stability than any polymer. The resistance and durability of PVF films to sunlight, chemical solvents, acid and alkali corrosion, moisture and oxidation are significantly improved. The film can be used as agricultural film, protective film of materials, packaging grease and corrosive substances, and also can be used as electrical insulation material.
During production and processing, the PVF film is extended laterally and longitudinally to form a molecular lattice, which greatly improves its physical properties. The PVF film can be doubled in wear resistance, moisture penetration resistance and elongation.
PVF film does not contain plastic agents, durable color stability, resistance to bleach, prevent powder and fungal growth. Its surface repulsive force, can prevent dust stain, easy to clean and maintain. Moreover, even the strongest detergents will not damage the PVF film.
PVF film can guarantee excellent performance from -70 ° C to 110 ° C, and the instantaneous temperature peak up to 200 ° C will not damage it. In addition, PVF film contains no plasticizer, so it has excellent aging resistance and maintains toughness and bending over a wide temperature range. Outdoor weathering tests of PVF films have been carried out by relevant testing institutions for more than 20 years.

The main purpose

1.PVF film and sheet metal composite: such as industrial plant exterior wall, roof or commercial building exterior wall protection panel, or used for highway sound insulation guardrail.

2.PVF film and PVC film composite: used for the space membrane structure of sports venues

3 PVF film is a good weatherproof material, with PVF film wrapped seal glass fiber or rock wool can greatly extend the service life of sound insulation bag.

4.PVF film has a good anti-UV performance, can be widely used in outdoor advertising, propaganda painting protective film.
