Dreamway B series Thermochromic Sun-Shading PVB interlayer (STI) is a kind of intermediate layer material for dry laminated glass. It is composed of about 80% polyvinyl butyral resin powder and 20% photothermal macromolecule nanomaterials. The interlayer is made by tape casting equipment. Various color systems can be synthesized according to different formulations. The base color of the STI can be determined at room temperature of 25 ℃. With the increase of temperature, the color of STI changes from light to deep.             

      STI has the same cohesiveness and safety as traditional PVB interlayer material. It can be combined with various glasses to make safety glasses with thermochromic, shading, heat insulation and energy saving.         

     STI meets the standard requirements of GB/T32020-2015 "Polyvinyl butyral interlayer“ and "JC/T 2166-2013 polyvinyl butyral (PVB) interlayer for laminated glass“, and has passed the test of  China National Safety Glass and Quartz Glass Test Center.
