How about Langton solar film?

Langdun solar film is very good because of the obedience of baking. Most of the front and rear windshields of cars are curved, so it is necessary to bake and shrink the solar film with a special baking gun to make it fit the glass.

Whether it is dry baking (baking with talcum powder) or wet baking (cleaning and baking with water), the solar film should be baked, and poor baking will cause the solar film to wrinkle. Spears are used in construction, and once baked and shaped, the effect is good.

Thermal insulation principle:

The birth of the solar film completely changed our naked life in the sun, but the heat insulation principle of the solar film did not come from the special project research in the laboratory. On the contrary, it came from the accidental discovery of the great inventor Thomas Alva Edison, who is known as the "king of invention in the world".

1888, after Edison invented the phonograph, he turned his attention to the development of movies. In the experiment, he took a series of photos and projected them on the curtains in rapid succession to create the illusion of movement.
