Abstract
The present disclosure relates, in some embodiments, to thermoplastic-olefin-based roofing membrane comprising a polymer blend. The polymer blend may comprise a thermoplastic olefin elastomer at about 30% to about 75% by weight of the polymer blend and a thermoplastic vulcanizate at about 10% to about 40% by weight of the polymer blend. The polymer blend may further comprise a thermoplastic polyolefin copolymer at about 5% to about 10% by weight of the polymer blend. In some embodiments, the thermoplastic olefin-based roofing membrane may be a single ply membrane configured to remain substantially free of swelling when exposed to an elastomer polymer compound. The thermoplastic olefin-based roofing membrane may be about 20 mils to about 40 mils thick. The thermoplastic-olefin-based roofing membrane may comprise a stretchability of about 14 lbf to about 30 lbf.
