PVB Film (Automotive Grade)

Product introduction

Brief introduction

The front windshield of an automobile is laminated glass, which is combined by a 0.76mmPVB intermediate film and a heat-bending glass of the same thickness as two layers of glass. The PVB intermediate film is shaped like a sandwich in the middle of two layers of glass. Less than ordinary tempered glass 10%, so that the weight of the whole car reduced 4 kg. Huakai PVB sandwich front windshield has a frame structure with safety performance, which, similar to the characteristics of air bags in cars, can slow down the inertia of collision and greatly reduce the fatality rate of people inside the car. Of course, Huakai PVB intermediate film has blue belt, green belt and gray, which can also effectively prevent the driver from being exposed to strong light by ultraviolet rays and greatly reduce the occurrence of traffic accidents. Besides, due to its poor thermal conductivity, Huakai PVB intermediate film is more comfortable than the car without the front windshield of PVB intermediate film. It saves the energy consumption of car air conditioning and prevents the driver from re-driving after a long time of sunlight irradiation.

security

When you think of making cars safer, you think of air bags that pop up automatically in the event of danger and seat belts around you. But there's one crucial accessory you tend to overlook: the front windshield of your car. In the past, we may have seen the scene of a major traffic accident will leave a lot of broken glass and the blood of the injured, which makes people see the tragedy! Now there is a car front windshield, the most important is the layer in the middle with special functions of Huakai PVB intermediate film, which is bonded with the glass and has excellent safety protection function. The car front gear is formed with PVB intermediate film and two layers of glass of equal thickness after high temperature and high pressure vacuum and other technologies. Its safety is reflected in, When the front windshield of a car is squeezed or impacted by the outside world, the fragments of the front windshield will not be scattered and hurt the innocent. The fragments will adhere to the PVB intermediate membrane with the shape of a spider web, even if all of them are broken on the ground, they will not be scattered, but also the shape of the whole windshield, coupled with the ingenious scientific design of the designer. Greatly reduce the injury of the injured, but also greatly improve the safety of the car.

anti-theft

When some people accidentally leave valuables in the car, such as cash, laptop, digital camera, etc., it will attract the eyes of the thief. The car with Huakai PVB laminated glass will double insure the car with high safety coefficient, so that the thief will not take advantage of it. Without PVB laminated glass, the thief only needs to hit the hand twice in 3 seconds with the hammer; For Huakai PVB laminated glass, it takes 30 seconds for the thief to hit the hand more than 18 times with the same force with a hammer. Compared with that, the laminated glass with Huakai PVB intermediate film is more secure.

Uv protection

Today, in the front windshield of the car at the top can be seen everywhere green or green a ribbon, this ribbon is called PVB intermediate film, in fact, this film is in the middle of two layers of glass, and is the whole sheet. Then why do you only see the top one? This is because the bottom is transparent, and after the high temperature and high pressure sandwich vacuum technology, you can't see the transparent color underneath. This green or blue has an important role, that is, it can absorb or reflect 99% of the UV, to protect the driver from strong light and harmful light exposure to provide a safe and comfortable guarantee.

Sound insulation

The laminated glass of Huakai soundproof PVB film can effectively reduce the sound of wind and noise outside the car body in the process of driving. In normal circumstances, the sound insulation effect of PVB intermediate film is 3 dB higher than that of ordinary PVB products. If the sound range of 2000 Hz is in the high-frequency noise zone, The sound insulation effect is 5 decibels higher than the general product, and the whole weight is reduced by 10%-12% compared with the toughened glass. The PVB intermediate film can also make the music in the car appear more melody, not polluted by external noise, bring quiet and comfortable driving environment to the driver, especially suitable for hospitals, libraries, concert halls, offices and other public places.
