Development Overview Of Thermal Insulation Film

The first generation: 1930s-coating and composite process membrane
Commonly known as tea paper, its main function is to block strong sunlight. This type of film has basically no thermal insulation effect and is only used for shading.
Second generation: 1960s-dyed film
The deep dyeing method adds an endothermic agent to absorb the infrared rays in the sun to achieve a heat insulation effect, but has no blocking effect on heat. The visible light transmittance is low, the clarity is poor, the heat insulation function decays quickly, and it is easy to fade.
Third generation: Early 1990s-metal reflective film
The aluminum layer is evaporated onto the substrate to achieve a thermal insulation effect. It has longer-lasting heat insulation, but the clarity is not high, which affects the comfort of the field of vision, and it is highly reflective.
Fourth generation: late 1990s-Weigu-intelligent spectral selection film
Through magnetron sputtering technology, advanced aerospace alloy materials such as nickel, silver, titanium, gold, and indium oxide are evenly sputtered on the high-tension PET substrate. The thermal insulation effect is long-lasting, and it also achieves high-definition, high thermal insulation, low reflection, and non-fading performance, and the UV protection coefficient reaches 99%. Multi-layer precious metal films are pasted on the inside of the glass to increase the explosion-proof coefficient.
Fifth generation: Amber optical nano ceramic insulation film
Nanotechnology is used to evenly sputter high-temperature-resistant and extremely stable ceramic materials onto high-tension PET substrates. The thermal insulation effect is significant and long-lasting, it is not easy to oxidize, and it definitely does not block the GPS. It truly achieves the perfect window film standard of non-oxidation, non-fading, non-blocking GPS, high heat insulation, high light transmittance, low reflection, long-lasting color and long life.
Sixth generation: Energy control induction film - the current representative brand is the German BMW original insulation film - Hanwei, Germany
Features: The total radiation variable of sunlight selects reflection technology; the constant amount of visible light passing through ensures clear vision while maximizing the total energy of reflected sunlight. It is similar to the principle of smart blinds to control and control light.
The differences between sixth-generation products and other products:
Sixth generation: Intelligence: It can be adjusted according to the intensity of light radiation energy to control the amount of energy passing through, just like an intelligent blind.
Other products: Constancy: Due to the characteristics of the material, the proportion of energy passing through is constant, just like a sieve with a fixed mesh.
