SPD smart glass is a safety intelligent glass customized using SPD specific EVA film laminating technology. Customization of irregular shapes is possible, and flat surfaces can be perforated and cut into various shapes. According to the needs of the scene, curved smart glass can also be made. Curved smart glass is divided into curved steel smart glass or hot bending smart glass (in general, only hot bending smart glass can be made for diameters less than 1 meter). In some cases, PC can be used instead of glass, which also increases the process of insulating glass. When made into insulating glass, the product can have better sound insulation and heat insulation effects. It is worth noting that SPD materials have a maximum temperature resistance of 105 degrees and require the use of RuShui specific SPD film.
