One. Light transmittance and definition
This is the car uses the function with safety of drive a vehicle is affected the mainest in film, paper of a few suns (common weighs dark brown paper) although color is very deep, but light transmittance is extremely low however, after affixing film black breathe out breathe out, the lens after falling in light of an aperture must be dug on side window film, this is quite dangerous to safety of drive a vehicle. And film of fine heat insolation of car explosion proof, no matter color depth, definition is very high, can be not only when nightly drive a vehicle from the back come the intense bewildered reflection of the lens after car headlight illuminate is falling is abate, be in namely dirty night drive a vehicle, back a car or tune as much the line of sight is good. So, when the user is sticking film, do not choose the film with too small light transmittance commonly.
2. Heat proof quality
Adiabatic rate is to reflect film of car explosion proof the main index of heat proof quality, at present the explosion proof film such as division of heart of the dragon film on the market, AC, Lei Peng, adiabatic rate is in commonly 50% above, tall pervious to light, tall heat insolation, can raise the comfortable sex of drive a vehicle already, can reduce air conditioning bear to achieve an oily goal again. And contrary a lot of film, only however light transmittance does not have adiabatic rate, index of a little flat even what also is done not have. When so consumer is sticking film besides should view the index such as adiabatic rate normative, the most reliable method holds off the sun with the glass that sticks film namely or pass illuminate of iodic tungsten lamp, check adiabatic effect directly with face or hand.
3. Explosion proof function
The material of general sun paper or film of inferior explosion proof differs with true explosion proof film character, its film is very thin very soft, lack enough tenacity, do not be able to bear or endure ultraviolet illuminate, easy ageing hair is fragile, cannot have explosion proof effect when encountering accident collision. The explosion proof film of quality goods is met after vitreous burst velamen cement and unapt splatter person. Should use when exceeding film of strong explosion proof, if encounter gangster club to attack car window to grab the article inside car or theft car, return the strength that can increase beat back, make glass is attacked not easily to break, and special ballproof film can be used at carrying the ballproof glass of bank note car is mixed to prevent cruel patron wagon to go up more.
