Polyvinyl Butyral Resin Pvb Resin
PVB has special bonding and high transparency to inorganic and organic glass. It can be used as a sandwich material for safety glass. Safety glass made of PVB as a sandwich has been widely used. The windshield of cars and airplanes. Because the safety glass made of PVB as the interlayer has strong impact resistance, high transparency, water resistance, aging resistance, and can be used in an environment of minus 60 ° C, in addition to the use of plexiglass as a transparent material. product.
