According to Japanese media reports, Japan Ecological Insulation Film Co., Ltd. has developed a "metal sputter film" as a new window film. The window film is coated with an aluminum metal film, which can reduce 99% of ultraviolet rays and 90% of infrared rays. It can be used to prevent heat stroke in summer and keep the environment cool.
According to the company, the metal sputtering film uses a sputtering technology to form a metal film with uniform heat dissipation. In addition, the film has successfully improved its durability to 15 years by sputtering technology. Compared with the traditional window film, the film has a longer service life and reduces the trouble of daily replacement.
In addition, the window film also has a privacy effect. You can see bright outdoor scenes from the inside, but it is difficult to see the room look when viewed from the outside.
It is understood that window film is a multilayer functionalized polyester composite film material that can be installed on indoor glass surfaces or exterior glass surfaces in residential and commercial buildings, automobiles, ships and marine applications. Therefore, the global window film manufacturers are constantly improving the performance of window film products and expanding their application fields under the market demand.
Not long ago, Toray Japan announced that it has developed a nano-laminated film "Picasus UV" that has a high UV shielding rate of 99.99% and also has transparency.
Relevant information shows that "Picasus UV" is made by laminating two kinds of polyester polymers. Through the design of thickness or arrangement, it can give it any function of reflecting or absorbing ultraviolet light. Due to repeated reflection and absorption between many layers, it can block ultraviolet rays to about 400 nm, achieving an effect that cannot be achieved by films containing only ultraviolet absorbers, and greatly improving shielding performance. The visible light transmittance of "Picasus UV" is 92%.
