plastic material name

Plastics contribute to approximately 10% of discarded waste. "[51][52], The presence of plastics, particularly microplastics, within the food chain is increasing. As a result, polyethylene is in a wide variety of products. While plastics can be made electrically conductive, with a conductivity of up to 80 kS/cm in stretch-oriented polyacetylene,[14] they are still no match for most metals like copper which have a conductivity of several hundred kS/cm. Bis(2-ethylhexyl) adipate, present in plastic wrap based on PVC, is also of concern, as are the volatile organic compounds present in new car smell. [11] Common thermoplastics range from 20,000 to 500,000 amu, while thermosets are assumed to have infinite molecular weight. Here are the four common polyethylene densities: This density of polyethylene is ductile and used to make products like shopping bags, plastic bags, clear food containers, disposable packaging, etc. Polyethylene Terephthalate has excellent chemical resistance to organic materials and water and is easily recyclable. Acrylic is typically used in sheet form create products such as acrylic mirrors and acrylic plexiglass. The first application was for bristles for toothbrushes. Typical stabilizers thus absorb UV light or function as antioxidants. In 2011, it was reported that "almost all plastic products" sampled released chemicals with estrogenic activity, although the researchers identified plastics which did not leach chemicals with estrogenic activity. The transparent plastic can be made colored and fluorescent, abrasion-resistant, bullet-resistant, UV-tolerant, non-glare, anti-static and many more. [20] Parkesine won a bronze medal at the 1862 World's fair in London. [105] Because hydrogen chloride readily combines with water vapor in the air to form hydrochloric acid,[106] polyvinyl chloride is not recommended for long-term archival storage of silver, photographic film or paper (mylar is preferable).[107]. Polyethylene Terephthalate (PETE or PET) 6. Nevertheless, this is a developing field. [49] Much of this material may persist for centuries or longer, given the demonstrated persistence of structurally similar natural materials such as amber. Toward the end of the century, one approach to this problem was met with wide efforts toward recycling. It finds much current use as the substance of toy figurines and novelties. This category includes both commodity plastics, or standard plastics, and engineering plastics. Subsequently, polyamides 6, 10, 11, and 12 have been developed based on monomers which are ring compounds; e.g. [25] In 1933, polyethylene was discovered by Imperial Chemical Industries (ICI) researchers Reginald Gibson and Eric Fawcett. Early plastics were bio-derived materials such as egg and blood proteins, which are organic polymers. In around 1600 BC, Mesoamericans used natural rubber for balls, bands, and figurines. The colorant must satisfy various constraints, for example, the compound must be[36] chemically compatible with the base resin, be a suitable match with a color standard (see e.g. The plastic material was patented by Alexander Parkes, in Birmingham, England in 1856. Hans-Georg Elias "Plastics, General Survey" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. An economical alternative to HDPE or ABS, polypropylene plastics offer an excellent balance of thermal, chemical, and electrical properties. The final result was unsuitable for the original purpose. The first fully synthetic rubber was synthesized by Sergei Lebedev in 1910. In the space race and nuclear arms race, Caltech researchers experimented with using synthetic rubbers for solid fuel for rockets. This page was last edited on 29 November 2020, at 21:54. [42] Research in Environmental Health Perspectives finds that BPA leached from the lining of tin cans, dental sealants and polycarbonate bottles can increase body weight of lab animals' offspring. Depending on their chemical composition, plastics and resins have varying properties related to contaminant absorption and adsorption.
