The 3M automobile film is flame retardant, and the residue-free adhesive is removed as 3M active adhesive, which is flame retardant and environmentally friendly and easy to remove without residue. The classic and distinguished models of 3M automobile film belong to 3M advanced automobile film product series, all of which are formulated with environmental protection, anti-mildew and flame retardant. Compared with the classic model, the distinguished model has larger total thickness and coil diameter, so the overall service life and foot comfort are better. Jing Rui series of 3M automobile heat insulation film adopts unique multi-layer optical film nanotechnology, with more than 200 layers combined into one, and the thickness is less than post-it notes.
The origin of car movies
1966, 3M obtained the world's first patent for thermal insulation film, and it is one of the few manufacturers in the world that can independently produce thermal insulation film from beginning to end. At present, there are many manufacturers with patented technology of thermal insulation film in the field of optical technology, and there are also many manufacturers with world patents. On average, more than three new products of thermal insulation film are introduced every year, and each patented technology gives thermal insulation film different unique functions.
