Thermochromic Film

About

Thermochromic Film

    Smart thermochromic film is an intelligent light control product whose color changes with the change of ambient light thermal intensity. It not only has the functions of heat insulation, sunscreen and UV protection, but also it has the same safety and adhesiveness as the traditional PVB laminated materials. Whats more, smart thermochromic film can be laminated into smart thermochromic glass by glass laminating process. A color-changing glass that can sense climate change is a glass that is full of vitality. It is a natural dimming product preferred for cars, yachts, building doors and windows, lighting roofs, etc.

At morning and evening, film has different color. At different seasons, film has different color.

High photothermal intensity. Weak photothermal intensity.

Intelligent sunshade

According to the ambient light heat intensity, our film could automatically adjust the light transmittance and create a comfortable light space for you. At the same time, the infrared blocking capacity changes with the cumulative light and heat intensity. In summer, the light intensity is large and the irradiation time is long. Our film could lower the infrared transmittance and get obvious heat insulation effect . In winter, the light intensity is small and the irradiation time is short. Our film could rise the infrared transmittance and get more solar energy.

Heat insulation

In winter, our film could keep far infrared rays and heat indoors which are generated by human bodies, household appliances, air conditioners. By this, our indoor temperature is constant. In the summer, the far-infrared (heat source) is blocked outdoors so that indoor is cool. Our home life will be like spring all seasons which greatly reduces the load of air-conditioning and heating and saves electricity costs.

Energy-saving and environmental protection:

Blocking 99.5% of ultraviolet rays and 85% of infrared rays which can avoid the strong sunlight harm to the people, cabinets, interiors, clothing . At the same time our film could lower the temperature inside the car and indoor .It is really energy-saving, power saving and environmental protection.

Safe and Explosion-proof

Anti-seismic, Explosion-proof, harm reduction .With above advantages a invisible protection net has been built.

Appearance chaning

Color changing by light. The building glass will have different colors in different time.

Durable

The tinted glass is a laminated glass that has been tested for radiation resistance and has a lifetime of up to 30 years.

A multi-use product

It could be used at four seasons and have following functions: all-round shading, environmental protection, health and safety.

Sound insulation and noise reduction

It has very good sound insulation effect and could protect you from outside noise. Silent environment could bring you a good dream.

Temperature warning

Intelligent color film can indicate the temperature change through the penetration of light.

Applications

    It can be used in places where glass is used, such as glass curtain wallsun room, lighting roof, building doors and windows, flower sheds, etc.

Product principle

    When receiving different stimulus of light and heat intensity, and the photo-sensing temperature factor presents different angles and orientations.

    When the light-heat intensity becomes stronger, the nano photosensitive temperature factor element exhibits a dense and regular distribution after absorbing more energy.By this,film could obstruct light transmission and the glass color changes from shallow to dark. It is like wearing a color-changing sunglasses to the window, blocking the glare, protecting the eyes and blocking the heat. A warm atmosphere is created for you and your family.

    When the intensity of light and heat becomes weaker, the nano photosensitive temperature factors gradually recover disorderly scattered arrangement, and the light easily passes through. The color is restored from the shallow depth to the original state. The process will not affect your driving, boating, working or enjoying the scenery. Our film could protect you and your family and create a harmonious living environment.

Product Structure

    Smart thermochromic laminated glass could be used alone as a safety glass, or it can be further compounded into other glass.

    The hollow glass with the combination of smart thermochromic laminated glass and LOW-E glass has the best energy-saving effect, and it is recommended to give priority to it.

Production Method

    Smart thermochromic laminated film is suitable for the preparation of various dry laminated glass on the market.
