As in metal alloys the properties of a TPO product depend greatly upon controlling the size and distribution of the microstructure. PP and PE form lamellar crystallites separated by amorphous regions that can grow into a variety of microstructures ranging from single crystals from dilute solution crystallization to fiberous crystals and shish ...
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 ...
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 ...
Membranes have to provide enough mass transfer area to process large amounts of feed stream. The selected membrane has to have high selectivity properties for certain particles; it has to resist fouling and to have high mechanical stability. It also needs to be reproducible and to have low manufacturing costs.

A properly designed and installed extensive green-roof system can cost $108–$248/m 2 ($10–$23/sq ft) while an intensive green roof costs $355–$2,368/m 2 ($33–$220/sq ft) However, since most of the materials used to build the green roof can be salvaged, it is estimated that the cost of replacing a green roof is generally one third of the ...
