Damp degree, against weather can be resisted and be radiated at interior any solar exposure including UV, all show in various application fields fabulous
Obdurability and persistence to make film ontology that there is preferable elastic shock sucking function can resist severe impact.
The utility model is further arranged to: being gone to a grassroots level between macromolecule polyurethane resin layer in the PVB film
It is provided with aramid layer.
By using above-mentioned technical proposal, PVB film go to a grassroots level be provided between macromolecule polyurethane resin layer it is poly-
Amide layer, to improve film ontology tensile strength and anti-shearing force intensity.
The utility model is further arranged to: being provided with glass between base and TPU ink layer on the PVB film
Fibrous layer.
By using above-mentioned technical proposal, it is provided with glass layer between base and TPU ink layer on PVB film,
The good insulating of film ontology, heat resistance are strong, corrosion resistance is good, high mechanical strength to making, and then improve film ontology
Practicability.
