Huakai PVB film is composed of polyvinyl butyral resin, plasticizer, agent through a polymer materialplasticizing tape casting, widely used in the field of building safety glass, automotive safety glass, solar photovoltaic component packaging film, coating, paint, printing ink. Using a special formula PVB? Film can also be used in aerospace, military and new and high technology industries. PVB film characteristic - Safety:reinforced glass elastic, reduce the impact of external force, ensure personal safety against accidentaldamage. - Security: PVB laminated glass is very strong, even if the crack, with the middle layer of glass firmlystick together, still can maintain structural integrity. - insulation resistance: PVB film with damping function on acoustic propagation, can effectively restrain the noise, sound insulation effect is very obvious. - anti UVproperties: PVB film can absorb more than 99% of the ultraviolet. Effect: reduce, energy saving sunlight through to PVB laminated glass in building. The same thickness, laminated glass block heat dark low transmittance of PVB film made of stronger.
