Safe, comfortable and energy saving is the requirement for vehicle glass in order to achive and balance all functionalities. Vehicle glass will need sun-shading film+glass to meet safe and temperature requirement. But sun-shading film will crack and foam with time, while unqualified sun shading film has the disadvantage of bad smell to pollute air, absorbed heat, and raise car temperature. The film laminating and film replacement cost is also very high. TPG can solve all above problems perfectly.
