2. Thermoplastic olefin - Wikipedia

   en.wikipedia.org/wiki/ThermoPlastic_Olefin

   This type of material is non-rigid, and is sometimes called TPR for ThermoPlastic Rubber. To increase the rigidity of a TPO blend, fillers exploit a surface tension phenomena. By selecting a filler with a higher surface area per weight, a higher flexural modulus can be achieved. Specific density of TPO blends range from 0.92 to 1.1.

   Membrane roofing is a type of roofing system for buildings, RV's, Ponds and in some cases tanks. It is used to create a watertight covering to protect the interior of a building. Membrane roofs are most commonly made from synthetic rubber, thermoplastic (PVC or similar material), or modified bitumen. Membrane roofs are most commonly used in ...

4. Thermoplastic elastomer - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_elastomer

   Thermoplastic olefins (TPO) are increasingly used as a roofing material. [8] TPEs are also widely used for catheters where nylon block copolymers offer a range of softness ideal for patients. Thermoplastic silicone and olefin blends are used for extrusion of glass run and dynamic weatherstripping car profiles. Styrene block copolymers are used ...

   Depending on the size of the roof and the experience of the crew, it is possible to remove old shingles and apply new ones on 2-3 houses in one day. Life span varies. Use only on slanted roofs. [4] Rubber shingle, an alternative to asphalt shingle, slate, shake or tile. Made primarily of rubber, often recycled tire-derived rubber.

6. Flat roof - Wikipedia

   en.wikipedia.org/wiki/Flat_roof

   TPO roofing systems feature strong seams that are heat-welded, providing superior seam strength and reducing the risk of leaks compared to other roofing systems with adhesive or tape seams. A TPO roof system can be fully adhered, mechanically fastened, or ballasted, although TPO roof systems are rarely ballasted, since the ballast covers up the ...

7. Asphalt roll roofing - Wikipedia

   en.wikipedia.org/wiki/Asphalt_roll_roofing

   Asphalt roll roofing or membrane is a roofing material commonly used for buildings that feature a low sloped roof pitch in North America. The material is based on the same materials used in asphalt shingles ; an organic felt or fiberglass mat, saturated with asphalt , and faced with granular stone aggregate.
