PVC (polyester fiber) film material Classification According to the intensity level, it is divided into grades Explain that the fabric base material of PVC film material should be polyester and polyamide fiber fabric. The coating is mainly polyvinyl chloride (PVC) resin. According to the functional requirements, the weight of different coatings should be between 400 1500g/m2. The surface layer should be polyvinylidene fluoride resin (PVF) and polyvinylidene fluoride resin ( PVDF), polypropylene resin (ACRYLIC), silicone resin, etc., and should have the function of improving the self-cleaning and anti-aging properties of PVC film materials. The thickness of the PVC film material should be greater than 0.5mm. The surface layer should have stable anti-corrosion and anti-ultraviolet eroding ability during the warranty period, and should have self-cleaning performance. Selection points 1) The surface layer of the PVC film material should have stable anti-corrosion and anti-ultraviolet eroding ability during the warranty period, and the surface should have self-cleaning performance. 2) When the PVC film material reaches the melting point in a fire environment, a molten hole will appear, and the boundary of the molten hole will burn and spread, but no open flame will be produced. According to my country's GB8624 "Classification Method for Combustion Performance of Building Materials", it is designated as a Class B1 flame-retardant material. 3) The color, light reflection and transmittance of PVC film materials should meet the requirements of the following table. Film material type Film surface color Light reflectance (%) Film surface transmittance (%) PVC film material Milky white, translucent 75 85 613 Color 45 55 4 6 4) The main performance comparison of four different surface materials of PVC film materials is shown in the table below. Main performance: PVC film material on the surface of polypropylene resin, PVC film material on the surface of PVDF can be spliced PVC film material on the surface of PVDF not spliced, PVC film material on the surface of PVF-film Manufacturer warranty period 3-7 years 10 years 10 years 10 years Aging resistance low fair good good UV resistance low fair good good Corrosion resistance low fair good good Softness good good good good Foldability Foldable Foldable Foldable Unfoldable Self-cleaning performance low good very good very good Splicing method Direct splicing Polishing or pasting splicing strip splicing Polishing or pasting splicing strip splicing Material price low high high high
