Product Description

Introduction:

Rare earth PVB interlayer film (RE film)  is a macro molecule material which produced by extrusion using PVB resin, plasticizer and a special rare earth additives. With the rare earth additives ,our RE film is not only with high visible transmittance, super anti-penetration but also with high Infrared Rejection Rate and Ultraviolet Rejection Rate, which can shield out the heat and sound. The rare earth metals in our RE film can easily insulate infrared and ultraviolet rays as we transform the nanoscale molecule structure of the metal.  This structure targets the specific characteristics of infrared and ultraviolet light. Solar radiation heat energy is absorbed into the RE film surface and  transformed into physical heat energy then is carried away by air convection.
The major application of RE film  is laminated safety glass used on automotive windshields, architectural glass as well as the bullet proof glass.
