Abstract
An automotive sealant composite structure is provided. The composite structure includes a first piece comprising a first elastomeric component that includes an at least partially crosslinked rubber, a first olefinic thermoplastic resin component, and a second olefinic thermoplastic resin component. The second olefinic thermoplastic resin component includes a propylene copolymer that has (i) 60 wt % or more units derived from propylene, (ii) isotactically arranged propylene derived sequences and (iii) a heat of fusion less than 45 J/g. The composite structure also includes a second piece at least partially adhered to the first piece. Preferably, the second piece includes one or more thermoset ethylene copolymer rubbers. Preferably, the first piece is a corner piece and the second piece is a straight piece at least partially adhered to the corner piece, together constituting a vehicular window seal structure.
