The pvdf aluminum sheet price is a little higher than that of pe coated aluminum sheet because pvdf coating has longer service life and better weather resistance in exterior. The PVDF color coated aluminum sheet 3003 3004 3105 are usually applied in construction (aluminum composite panel, aluminum honeycomb panel, aluminum roofing sheet, fireproof panel, aluminum ceiling, shutters, roller shutter door, garage door, awning, drooping gutter), electronic appliances (computer case, electrical panel), lighting, furniture, etc.
We all knows that the price matched the quality most, so we can see that the PVDF coated aluminum sheet had better performance than PE costed aluminium sheet. The fluorocarbon PVDF is a coating of resin mainly referring to a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer. The chemical structure of the fluoric acid base is combined by a fluorine/carbon bond. This chemical structural stability and firmness make the physical properties of fluorocarbon PVDF coatings different from conventional coatings. In addition to the abrasion resistance in terms of mechanical properties, the impact resistance of PVDF color coated aluminum sheet has excellent performance, especially in the harsh weather and environment, showing long-lasting fading resistance and UV resistance. After the high temperature barbecue is formed into a film, the molecular structure in the coating is tight and has excellent weather resistance. Fluorocarbon PDVF coatings can be classified into conventional fluorocarbon and nano fluorocarbon coatings according to the surface film formation structure.
