Abstract
The present invention is in the field of polymer interlayers used in multiple layer glass panels, and specifically the present invention is in the field of various performance enhancing agents for polymer interlayers and methods of effectively incorporating such performance enhancing agents into interlayers.
Claims20
An interlayer, comprising:
- a polymer stack comprising a first polymer sheet, wherein said first polymer sheet is substantially free of a first performance enhancing agent;
- and,
- a second polymer sheet disposed in contact with said polymer stack, wherein said
- second polymer sheet has a thickness of less than 0.4 millimeters and comprises
- said first performance enhancing agent.
2 more elements
An interlayer, comprising:
- a polymer sheet, wherein said polymer sheet comprises an agent region and a non agent region, wherein said agent region comprises a performance enhancing agent and has a thickness of less than 0.4 millimeters.
A method for making a polymer sheet, comprising:
- coextruding a first melt and a second melt to form said polymer sheet, wherein said polymer sheet comprises an agent region formed from said first melt and a non agent region formed from said second melt, wherein said agent region has a thickness of less than 0.4 millimeters, and wherein said first melt comprises a performance enhancing agent.
