Frech Green PVB Film For Windscreen Safety Glass
Qingdao Jiahua Plastics Co., Ltd . was founded in 1992. And we are the first professional PVB film producer in China. Our band is SAFLAYER. After more than 20 years, Jiahua is at the leading position in the PVB film market based on imported producing lines, rich experience and mature technology. Yearly output up to 8000 Mts.
Our company's PVB film raw materials is self-produced PVB resin, never add any recycled material. We have advanced production equipment imported from the United States and France, and we have a professional technical team and more than 20 years of production experience of the above factors determine our excellent product quality.
Qingdao Jiahua not only produce the high qualified PVB film, but also provide considerable technical support for laminated machines by experienced R&D department.
Now Jiahua is engaged in the Research & Production in PVB resin, PVB film, plasticizer, and laminated glass to keep pace with the world market demands. Factory already passed the CE, ISO, SGS as well as the Test Report for PVB products. By conforming to Jiahua enterprise tenet, we hope to cooperate with you for improvement and excellent future!
JIAHUA PVB is produced by extrusion of PVB resin, plasticizer and additives. Due to its excellent transparency, heat resisting and elasticity, our PVB is widely used for laminated safety glass manufacture for automotive windscreen and architectural application.
PVB helps laminated glass to shield not only UV radiation but also sound and heat, making glass comfortable ,decorative and energy-saving.
Safety
Normal glass tends to shatter after strong impact. Due to the high adhesion of PVB film, the laminated glass fragments can adhere on the interlayer film without shattering. It would help to reduce the most of injuries or casualties.
Anti-penetration
Laminated glass cannot be easily segmented by common or normal glass cutter. Even with other heavy tools, laminated glass is still not easy to break. It helps to enhance the security in both architectures and automotives. Contradictory to laminated glass, tempered glass, those glass without PVB interlayer can be broken by either hammers or heavy tools.
Sound reduction
PVB laminated glass has a good sound insulation effect. Noise from outside is effectively shielded out, allowing users to stay away from disturbances.
Thermal resistance
PVB film can block infrared radiation and minimize the heating effect from sunlight. With stable colored PVB intermediate film in the laminated glass shall control the increasing heat by absorbing the UR(ultraviolet ray), visible light and IR(infrared ray).
UV resistance
PVB film reduces 99% of UV radiation, preventing sunburn and skin cancer even under long exposure of the sun. So human can gain extra protection from UV. Apart from this, it also prevents depigmentation of furniture in houses with PVB laminated glass.
