The thicker barriers of transparent plastic used in teller's windows and barriers in banks are also polycarbonate. So-called "theft-proof" large plastic packaging for smaller items, which cannot be opened by hand, is typically made from polycarbonate.
Plastic-eating microbes also have been found in landfills. [96] Nocardia can degrade PET with an esterase enzyme. [97] The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic found in CDs. [98] [99] Futuro houses are made of fiberglass-reinforced polyesters, polyester-polyurethane, and PMMA.
Polycarbonate is independently developed by Hermann Schnell at Bayer and Daniel Fox at General Electric. 1954: Polypropylene is discovered by Giulio Natta with production starting in 1957 [1] 1954: Expanded polystyrene, used for building insulation, packaging, and cups, is invented by Dow Chemical. [1] 1957
The use of these compounds is diminishing due to restrictions on brominated flame retardants. The reaction of BPA with phosphorus oxychloride and phenol forms BADP, which is used as a liquid flame retarder in some high performance polymer blends such as polycarbonate/ABS mixtures that are used to form the casings for household electronics.

Polycarbonate (PC) PC is a clear plastic used to make bottles for milk and water. Five-gallon water bottles are a common application of PC. Polypropylene (PP) PP is used primarily for jars and closures. It is rigid and is a barrier to moisture. Polypropylene is stable at temperatures up to 220 °F (104 °C).
Dry cleaners use more than 300 million pounds of plastic film in the United States alone, according to a report from Beyond Plastics. You can also swap plastic hangers for wood, metal or ...
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
