ABSTRACT:
A high strength thermoplastic vulcanizate (TPV) composition is provided. The TPV includes a dispersed rubber component, a polyolefinic thermoplastic resin component, a propylene copolymer and mineral filler present in the amount of 20 wt % to 70 wt % based on total of the thermoplastic vulcanizate composition. Preferably, the propylene copolymer has 60 wt % or more units derived from propylene; includes isotactically arranged propylene derived sequences; and has a heat of fusion less than 45 J/g. Preferably, the mineral filler is halogen free and flame retardant. The high strength TPV can be useful for making a variety of articles for electrical, construction, automotive, and consumer applications, including fuel cell.
