Abstract
The invention relates to a composition adapted for use as a sealing strip in the manufacture of insulating structures. The composition includes a polymeric base material, a cross linking agent, an adhesion promoter and less than 10% tackifier. The invention further relates to an insulating structure including first and second panes with the sealing strip positioned therebetween.
Claims14
An insulating structure, comprising:
- a first pane;
- a second pane;
- and
- a sealing strip characterized by improved compression resistance and low moisture vapor transmission rates whereby no spacer or moisture vapor barrier is present therein, said sealing strip positioned between the first pane and the second pane, the sealing strip composition including:
- a polymeric base material including in combination compounds chosen from the group consisting of polyisobutylene polymers, polyisobutylene copolymers, brominated olefin terpolymers, butyl rubber copolymers and styrene butadiene copolymers;
- a cross linking agent chosen from the group consisting of, divalent salts of organic fatty acids, zinc stearate, zinc octoate, tin octoate and calcium stearate;
- an adhesion promotor, and
- a tackifier.
