只有1%的人才会选择正确的汽车隔热膜，大多数车主误以为颜色越深越隔热，很多车主总以为遮蔽了阳光，车内就会凉爽这是个错误的思想。
卡尔本茨安全膜至于为什么隔热，是拥有UV 金属层 纳米高科技技术 通过反射紫外线 红外线阻隔热能等达到降低热能传播。
可见光透过率VLT
简单的来说：就是人肉眼可见的光波穿过玻璃的比率，数值越高乐清晰 数值越低膜的颜色越深。高透光的前挡膜可以让视线更清晰，有助于行车安全。侧挡膜选择透光率在20%-40%左右更能起到隔热和行车安全的效果。
In short: it is the ratio of light waves visible to human flesh eyes passing through glass. The higher the value, the clearer the value, the lower the value, and the darker the color of the film. The highly transparent front barrier film can make the line of sight clearer and contribute to driving safety. The light transmittance of the side barrier film is about 20% - 40%, which can better play the effect of heat insulation and driving safety.
可见光反射率VLR
这个数值是被贴了膜的玻璃反射到外面的光化率，优质的安全膜低内反光，减少内饰的倒影，不影响视线 透明玻璃的可见光反射率在7%左右。This value is the photochemical rate reflected from the coated glass to the outside. The high-quality safety film has low internal reflection, reduces the reflection of the interior, and does not affect the line of sight. The visible light reflectivity of the transparent glass is about 7%.
亲爱的车主小伙伴们 你们了解了吗？总之一句话选择汽车安全隔热膜就要选择高透光率，低可见光反射率的。
