What is the structure of automotive heat insulation and explosion-proof film?
3 Answers
Automotive heat insulation and explosion-proof film consists of: anti-scratch layer, installation adhesive, high-transparency PET release film, composite adhesive, UV absorption layer, transparent PET safety base layer, colored PET safety base layer, and metal heat insulation layer. The functions of automotive heat insulation and explosion-proof film are: 1. In hot summer weather, the film can insulate heat, saving air conditioning energy; 2. In cold and humid winter weather, the film can reduce energy loss and maintain the interior temperature; 3. The film can block ultraviolet rays; 4. It can reduce glare, ensuring driving safety and comfort; 5. After installation, the interior decorations can avoid direct sunlight exposure, extending their lifespan and quality.
The structure of automotive heat-insulating and explosion-proof film is quite interesting. I've studied it before, and it generally consists of five layers: The outermost layer is a scratch-resistant coating to prevent daily wear and tear; then comes the UV-absorbing layer, responsible for blocking harmful ultraviolet rays; the middle part is the key component, like a metal or ceramic material layer that absorbs heat to keep the car interior from getting too hot; next is the polyester film layer, which is incredibly strong and can wrap around glass fragments to prevent explosions if the glass shatters; the innermost layer is a strong adhesive layer to ensure it sticks firmly to the window without falling off. Each layer is very thin, but they work together effectively, saving on air conditioning fuel costs and making driving more comfortable. When choosing a product, it's advisable to check the material type—ceramic ones are more resistant to signal interference.
As an average car owner, my understanding of the structure is: it has a wear-resistant top layer to protect against scratches, then a UV-filtering layer to block ultraviolet rays, with a heat-absorbing layer in the middle, such as metal or ceramic, which reflects heat to keep the car interior cool; the anti-shatter layer is a plastic film with high strength to prevent glass from shattering and causing injuries; and finally, there's an adhesive layer to secure it in place. After installation, it feels really comfortable—no more turning into an oven when parked in summer, no more burning seats when getting in, and it even extends the lifespan of the interior. I think when choosing a film, it's important to check if all the layers are complete; the standard five-layer version works best, so don’t go for cheap single-layer products.
