Product Description

Thermochromic Sun-Shading PVB interlayer (STI) is a kind of intermediate layer material for dry
laminated glass. It is composed of about *0% polyvinyl butyral resin powder and *0% photothermal macromolecule nanomaterials. The interlayer is made by tape castingequipment. Various color systems can be synthesized according to different formulations. The base color of the STI can be determined at room temperature of *5℃. 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/T*********5"Polyvinyl butyral interlayer and "JC/T ********3 polyvinyl butyral (PVB) interlayer for laminated glass, and has passed the test of China National Safety Glass and Quartz GlassTest Center.
