Abstract
A weatherstrip having a migration inhibiting layer including a butyl based elastomer, wherein the butyl based elastomer can include a blend of a halogenated butyl and EPDM. The migration inhibiting layer can be located on at least one of a dense portion and an expanded portion of the weatherstrip and is selected to substantially preclude the passage of decomposition products, thereby reducing odor emanation from the strip and discoloration from staining materials. The migration inhibiting layer may also include coloring agents thereby providing a colored weatherstrip.
