Abstract
A foam profile prepared by a process comprising the steps of foaming a thermoplastic vulcanizate, where the thermoplastic vulcanizate is prepared by a process comprising the step of dynamically vulcanizing a rubber within a mixture that includes from about 15 to about 95 percent by weight of the rubber and from about 5 to about 85 percent by weight of a thermoplastic component based upon the total weight the rubber and thermoplastic component combined, where the thermoplastic component includes from about 65 to about 90 percent by weight of a conventional thermoplastic resin and from about 10 to about 35 percent by weight of a random propylene copolymer based upon the total weight of the thermoplastic component.

A foam profile prepared by a process comprising the steps of:
- foaming a thermoplastic vulcanizate, where the thermoplastic vulcanizate comprises vulcanized rubber and from about 5 to about 85 percent by weight of a thermoplastic component based upon the total weight of the rubber and thermoplastic component combined, and where the thermoplastic component comprises from about 65 to about 90 percent by weight of a conventional thermoplastic resin and from about 10 to about 35 percent by weight of a random propylene copolymer based upon the total weight of the thermoplastic component.
A foam profile comprising:
- a foamed thermoplastic vulcanizate, where the thermoplastic vulcanizate comprises vulcanized rubber and from about 5 to about 85 percent by weight of a thermoplastic component based upon the total weight of the rubber and thermoplastic component combined, and where the thermoplastic component comprises from about 65 to about 90 percent by weight of a conventional thermoplastic resin and from about 10 to about 35 percent by weight of a random propylene copolymer based upon the total weight of the thermoplastic component.
