Using magnetron sputtering technology, precious metal particles including gold are evenly and densely distributed on the film surface to achieve all-round reflection and heat insulation. Taking advantage of the excellent stability of gold, the thermal insulation effect of dragon film Houyi can be more durable and stable. Using imported optical grade PET base material, it has low haze, high light transmittance and ultra-smoothness. At the same light transmittance, Houyi is clearer than ordinary window film. Driving on rainy days or at night will not affect driving vision, and can alleviate the discomfort of dazzling sunlight or night headlights on the eyes, effectively improving driving safety.

The heat insulation of the whole vehicle is the real heat insulation. With a full set of dragon film Houyi, together with the front and side baffles, the heat insulation effect is better and the electronic signals are ensured to be smooth. The Houyi side rear bumper adopts double-layer nano-matrix technology and double nano-insulation particles to effectively improve the heat insulation effect and maintain a comfortable temperature in the car.
