Light transmittance
This is the most important performance of the car film related to driving safety, it is recommended that users try not to choose the film with too low light transmittance, the window film, especially the film of the windows on both sides of the front row, the base material used in the front gear car film is clear enough, even if the color is darker, the scenery to see should be transparent, not dim, deformed. It is more appropriate to choose a light transmittance of more than 85%. At this time, the side window film does not need to be drilled and does not affect the line of sight, and when driving at night, the strong glare reflection of the headlights shining on the rear mirror can be weakened, which makes the eyes very comfortable. In addition, it can also ensure good visibility when driving, reversing, and turning around on rainy nights.
Thermal insulation rate
Considering the climatic factors of long summer, high temperature and strong sunshine in Guangdong, the thermal insulation performance of the window film should be high. A good quality car explosion-proof film can reflect infrared rays, so the temperature inside the car is much lower, which in turn will reduce the air conditioning load and save fuel. If the owner of the car judges, the solution is very simple, just use the film glass to block the sun, and use your face or hands to feel the thermal insulation effect.
Explosion-proof performance
This is also another important performance related to safety High-quality explosion-proof film itself has strong toughness, after the glass is broken, it can be firmly adhered to the film without splashing and hurting people, and its impact resistance is very strong. The inferior explosion-proof film feels very soft, lacks sufficient toughness, is not resistant to ultraviolet radiation, and is easy to age and become brittle.
Ultraviolet blocking rate
For high-quality membranes, this index is generally not less than 98%, and the high can reach 100%. The high UV blocking rate can effectively prevent people in the car from being exposed to excessive UV rays and burning the skin, and can also protect the car audio from sunburn. Many inferior membranes do not have this index, or are far below the 98% standard. This is also the main basis for the warranty period of the product.
