Thermal Polyolefin Roofing

Another low volume polyolefin is polybutene 1 pb 1.

Thermal polyolefin roofing. Tpo thermoplastic olefin is a single ply roofing system that consists of a thermoplastic polyolefin membrane. Now with it s added major price competitiveness versus epdm rubber. Since 1995 tpo roofing systems have fueled nearly all of the growth in single ply roofing. In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989 it s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners.
