Laminated glass is a composite glass made by sandwiching a tough polyvinyl butyral (PVB) intermediate film between the glasses, and processed by high temperature and high pressure. The toughness of PVB film is very good. When the laminated glass is violently impacted and broken by external force, the film layer will absorb a large amount of impact energy and make it attenuate quickly-the laminated glass is difficult to break down, even if the laminated glass is broken, the glass fragments are basically The upper is adhered to the film to keep the fragments on the entire laminated glass from falling off, so it becomes a real safety glass.
Safety: Due to the firm and tough bonding between PVB film and glass, whether it is installed vertically or obliquely, it can resist external impact and prevent upward penetration. Once the glass is damaged, its fragments will still stick to the intermediate film, which can avoid personal injury or property damage due to glass splashing, and the whole piece of glass remains intact and can continue to withstand impact and shelter from wind and rain.
Control ultraviolet rays: PVB film has the function of filtering ultraviolet rays, and the PVB interlayer film can absorb at least 99.5% of ultraviolet rays. The special PVB film can also make the laminated glass have the function of controlling sunlight transmission and prevent glare. So as to protect indoor furniture, plastic products, textiles, carpets, artworks, and collectibles from fading and aging caused by ultraviolet radiation.
Decorative effect: Yunlong paper or PET film that can print various patterns can be placed in the sandwich, which can create an elegant decorative effect.
Heat insulation and energy saving: It can effectively reduce the penetration of sunlight and reduce cooling energy consumption.
Bulletproof and explosion-proof: PVB has excellent toughness and can absorb and withstand the impact energy generated by bullets or even bomb explosions, so that bullets or shrapnel cannot penetrate.
