When purchasing steam insulation film, several performance indicators closely related to quality should not be ignored.
First, transparency and clarity
This is the most important performance of the vehicle film in terms of driving safety. It is recommended that users should not choose a film with too low transparency. The window film, especially the film on both sides of the front row, should have a transmittance of more than 85%. More suitable. At this time, the side window film does not need to dig holes and does not affect the line of sight. At night, when driving, the strong glare reflection of the rear headlights on the mirror can be weakened, which makes the eyes very comfortable. In addition, the line of sight can be guaranteed to be good when driving, reversing or turning around in the rainy night.
Second, thermal insulation performance
Insulation performance Insulation rate is an important indicator of the thermal insulation performance of window film. Insulation performance Insulation rate is an important indicator of the thermal insulation performance of window film. Considering the climatic factors of long summer, high temperature and strong sunshine in Guangdong, the window membrane insulation performance is high. A good quality car solar film can reflect infrared rays, so the temperature inside the car is much lower, which in turn reduces the air conditioning load and saves fuel. If the car is mainly judged, the method is very simple. Just use the film-coated glass to block the sun, and use your face or hand to feel the heat insulation effect.
Third, explosion-proof performance
Explosion-proof performance is another important feature that involves safety. The high-quality thermal insulation film itself has strong toughness. After the glass breaks, it can be adhered to the film without splashing and injuring people, and its impact resistance is very strong. The inferior heat-insulating film feels soft, lacks sufficient toughness, is not resistant to ultraviolet radiation, and is prone to aging and brittleness.
Fourth, the UV blocking rate
For high quality membranes, this indicator is generally not less than 98% and high up to 100%. The high UV blocking rate can effectively prevent people in the car from being exposed to excessive ultraviolet rays, burn the skin, and protect the car's sound from being sunburned. Many inferior membranes do not have this indicator, or far below the 98% standard.
Five, color
Colors can be matched according to body color and personal hobbies. It is usually lighter green, sky blue, gray, brown, natural color and other colors that are more comfortable for the eyes.
Sixth, film surface scratch resistance
The high-quality and high-grade film surface has an anti-scratch layer, which can protect the film surface from being scratched under normal use.
Seven, shelf life
Generally, the membranes produced by regular manufacturers have a long quality guarantee period, usually 5 years. Some high quality membranes have a shelf life of up to 8 years.
