what is the function of eva dimming film?

eva dimming film is a new type of optical material. it is a polymer material made of polyvinyl alcohol ether alcohol anhydride. it has the characteristics of dimming, anti-ultraviolet, and heat insulation. used in windows and optical components of buildings, vehicles and electronic products, it has the following functions:

1. dimming: eva dimming film is essentially an electronic liquid crystal unit film that can change its transparency through current stimulation to achieve different brightness adjustments, adapt to visual needs under different brightness light conditions, and bring a more comfortable light environment. .

2. anti-ultraviolet: eva dimming film can effectively block ultraviolet rays and prevent buildings, vehicle interior accessories and electronic products from being exposed to ultraviolet rays to cause discoloration, aging and other phenomena.

3. thermal insulation: eva dimming film can effectively isolate heat transfer, reduce the temperature inside buildings, vehicles and electronic products, improve comfort and reduce energy consumption.

4. improve privacy: eva dimming film can effectively reduce the see-through effect and improve the privacy of windows and optical components.

5. protect the environment: eva dimming film can reflect part of the light, reducing sunlight and light exposure indoors and in cars, thereby reducing the emission of greenhouse gases such as carbon dioxide and helping to protect the environment.

taken together, eva dimming film has a wide range of applications and can provide people with a more comfortable, healthy and environmentally friendly light environment in the fields of construction, vehicles and electronic products.
