Product Characteristics:  
1. Safety. As a type of safety glass, laminated glass, when broken by impact, will have its shattered fragments adhere to the film, keeping the broken glass surface neat and smooth. Due to the adhesive effect of the PVB film sandwiched between the two pieces of ordinary glass, it will not produce sharp fragments that can injure people like ordinary broken glass.  

2. Sound insulation. The sound-insulating and sunlight-controlling properties of the PVB interlayer film make laminated glass a building material with energy-saving and environmental protection functions. It can block吻合噪声 (coincidence noise) in the 1000-2000 Hz frequency range that can penetrate ordinary glass.  

3. Strong UV blocking ability. It can block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum.
