DuPont solar film is a high quality automotive film.
It was developed by DuPont in the United States and has multiple functions such as excellent thermal insulation, UV protection, privacy protection and explosion protection . As a result, it is known as one of the representatives of high-end vehicle wraps.
One part, the thermal insulation of DuPont solar film is one of its main selling points. The sun is strong in summer and the temperature inside the vehicle is likely to be too high. DuPont solar film can block more than 90% of heat, preventing this phenomenon. Therefore, it is very suitable for use in regions with warmer summer climates such as the South.
On the other hand, DuPont solar film also offers excellent UV protection. Ultraviolet rays can cause serious damage to the facial skin and eyes of car passengers, and the solar film can filter more than 99% of ultraviolet rays, thereby protecting the health and safety of people to a certain extent. edge of the car.
In addition, DuPont solar film also has good anti-theft and anti-explosion functions. When a window is damaged, the film forms a film network to preventGlass fragments from flying and harming people. Therefore, DuPont solar film is a high-end automotive film with many practical functions and a relatively high price.
Features of DuPont film:
First of all, DuPont film has extremely high tensile strength and modulus and can withstand a high intensity stretching and extrusion pressure. . This property makes DuPont film an excellent packaging material to protect the safety and freshness of products such as food and pharmaceuticals. In addition, DuPont membrane can also be used to make shock-resistant and shock-absorbing materials such as inflatable mattresses and air cushion bags.
Second, DuPont membrane has excellent chemical resistance and can resist the erosion of a variety of chemicals such as acids, alkalis, salts andorganic solvents. This performance makes DuPont membrane an excellent building material, which can be used to make waterproof, moisture-proof, flame-retardant, thermal, sound-proof and other materials. In addition, DuPont membranes can also be used to make energy materials such as solar panels and fuel cells.
Finally, DuPont film has excellent surface transparency and flatness, as well as excellent surface finish and anti-vibration properties. This property makes DuPont film an excellent display material and can be used to manufacture high-quality display devices such as LCD displays and OLED displays.
