PVB film production

Product introduction

PVB laminated glass 

PVB interlayer film is a glass material comprises a polymer resin, polyvinyl butyral, a plasticizer DHA plasticized by extrusion molding. PVB laminated glass film thickness is 0.38mm and 0.76mm two kinds of inorganic glass has good adhesion, with a transparent, heat, cold, humidity, high mechanical strength properties. PVB interlayer film is mainly used for the glass is sandwiched between two pieces of glass into a layer of polyvinyl butyral PVB film as a main component. Because of PVB laminated safety glass, insulation, noise control and isolation UV and many other features, widely used in construction, automotive and other industries. 

PVB laminated glass has the following five characteristics 

First, security: When subjected to external impact, the resilient intermediate layer has a shock absorbing effect, prevent the penetration impact object, even if the glass is damaged, only the generation of fine cracks like spider, which is firmly adhered debris the middle layer, will not fall off scattered wounding, and may continue to use until a replacement. 

Second, anti-theft: PVB laminated glass is very tough, even if the thieves knocked the glass cracked due to an intermediate layer with glass firmly adhered together remains integrity, so that thieves can not enter the room. After eliminating the need to install laminated glass guardrail, save money and also get rid of a sense of beauty of the cage. 

Third, Sound insulation: Due to the acoustic PVB film has a damping function, PVB laminated glass can effectively inhibit the propagation of noise, especially those located in the installation of laminated glass, the sound insulation of buildings airports, railway stations, busy streets and roads on both sides very obvious. 

Fourth, PVB laminated glass UV performance: PVB film can absorb more than 99% of ultraviolet rays, thereby protecting the indoor furniture, plastic products, textiles, rugs, artwork, antiquities or merchandise from UV radiation occurs fading and aging. 

Five, energy: PVB film made of laminated glass building can effectively reduce sunlight through. Same thickness, the ability to use low transmittance of laminated glass PVB dark barrier film made of heat more. At present, the domestic production of laminated glass is with a variety of colors.
