Polypropylene based thermoplastic polyolefin (TPO) roofing membranes represent the fastest growing polymer technology in the commercial roofing industry. They offer the best attributes of other flexible single-ply membranes available today – EPDM and PVC – but without the limitations of either.
TIEMPO™+ 2000 TPO membranes from Dow Roofing Systems are formulated from a proprietary compound of ethylene propylene rubber and polypropylene. They feature exceptional weatherability, flexibility and low-temperature properties, along with heat weldability, tear-, puncture-, abrasion- and chemical-resistant properties. Because the olefinic polymer is completely thermoplastic, it can be fabricated and hot-air welded throughout its rooftop life.
