At present, the company manufactures more than 30,000
types of such windshield, covering nearly all auto types already launched into
the market. The windshield of the largest specification is 2700mm×2300mm laminated windshield for coach. Sixty percent of
the products are for export and 40% of them are sold in China.
Characteristic
●Excellent Safety Performance
Since the PVB films adhere tenaciously to the out-layer glasses, it can resist
the penetration during accidental crash as the car is travelling at a high
speed. When the glass gets broken by impact force, the broken pieces will be
stuck by the tough PVB film, which can prevent the broken pieces from flying
and falling. The whole glass will be kept perfectly. Therefore, personal injury
caused by flying of falling broken pieces can be avoided while the cars can
keep running. In this case, traffic accidents can be avoided and personal
safety is effectively ensured.

● Sound
Insulation
The PVB film in laminated glass for automobiles
can damp sound waves, avoid effects on persons in automobiles exerted by noise
transmission when the car is running at a high speed, as well as noticeably
improve the environment in the cars. It can produce better sound insulation
effects than common glass and insulating glass.
●Anti-ultraviolet
Radiation
Laminated glass for automobile has the capability
of lasting resistance to ultraviolet radiation. The 6mm float glass can resist
ultraviolet with the wavelength of shorten than 380mm. It can resist 29% of
ultraviolet rays. However, clear laminated glass for automobiles with the same
thickness can resist more than 99% of ultraviolet rays. Thus, it protects
decoration in the car from fading and aging caused by ultraviolet radiation.
