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.

1. Package and delivery

• Package                                                                                                        Finished PVB film shall be separated by PE film, then packaged with aluminum foil vacuum bags and then placed in the wooden case or fibre can.
• Delivery                                                                                       In 15 days after receive the prepaid, if there is no other case.
