Abstract: Broadly, the present invention provides a thermoplastic vulcanizate which can be readily processed into sheeting material for covering a roof that is both flexible and highly elastic. Where other thermoplastic elastomeric compositions have either been too stiff to act as roofing membranes or not processable due to their melt flow characteristics, the present thermoplastic vulcanizate employs a polypropylene random copolymer resin and a polyethylene random copolymer resin having about 10 to about 35 percent by weight ?-olefin co-monomer units; together with a compatibilizing rubber and a peroxide-based cross-linking agent, to provide an effective membrane for covering roofs.

The apparatus includes a wheeled carriage having an upwardly extending push/pull bar. A power supply propels the wheeled carriage and energizes a heating assembly that generates a heated airflow sufficient to fuse the roofing membranes to one another. A nozzle is coupled to the heating assembly for directing the heated airflow between the two membranes. A variable pressure roller assembly is coupled to the carriage and has a single durometer material carried by an axle that may have different diameter sections. The roller passes over the at least one protruding fastener while still applying a uniform pressure so as to form a substantially continuous width seam except where interrupted by the protruding fastener.
