  • INTERLAYER WITH NONUNIFORM SOLAR ABSORBER
    Publication number: 20100068532
    Abstract: The present invention includes interlayers and multiple layer glazing panels comprising those interlayers, wherein the interlayers comprise an infrared absorbing agent that is dispersed in the interlayer in a nonuniform distribution. The nonuniform distribution of the infrared absorbing agent allows the interlayer to be used successfully in applications in which transmission of a minimal level of infrared radiation is desirable to allow for sensor communication through the glazing.

  • Polymer films comprising stabilized infrared absorbing agents
    Patent number: 7585436
    Abstract: The present invention includes polymer films that comprise lanthanum hexaboride and an epoxy agent. The lanthanum hexaboride and epoxy agent can be incorporated into or onto a polymer film in any suitable manner. The addition of an epoxy agent surprisingly provides a stabilization effect to the lanthanum hexaboride, which allows for the production of polymer films that advantageously absorb infrared radiation and resist environmental degradation. Polymer films thus produced have a significant number of applications, for example, but not limited to, display devices, protective coverings, and glazing film applications.

  • Interlayers Comprising Stabilized Tungsten Oxide Agents
    Publication number: 20090035583
    Abstract: The present invention includes polymer interlayers that are used in multiple layer glazing panels. Interlayers of the present invention comprise a thermoplastic polymer, a plasticizer, a tungsten oxide agent, and a stabilizing agent that prevents the degradation of the tungsten oxide agent. Interlayers incorporating such components have improved ultraviolet light blocking character, and also maintain optical quality over time.
