What is polycarbonate resin?
polycarbonate resin (PC resin) is a type of thermoplastic component used in the production of certain plastics. While the specific attributes of each resin vary according to its accurate composition and extraction method, each synthesized by a catalyst from monomers called hydrocarbons, in a process known as condensing polymerization. The chain reaction results in a covalent bond of one carbon atom connected to three oxygen atoms, with small water molecules being moved to form a final polymer with high density and impact strength. Thanks to these properties, polycarbonate resin is suitable for the production of a wide range of products that require exceptional heat and resistance to compact discs, hockey masks, glasses, car parts, bullet -armor, medical and air equipment and Parts for the American National Aeronautics And Space Administration.
Many products, such as the above, are produced by subjugation of polycarbonate resin into a forming injection process in which the polymerized material solidifies inside or died and permanently becomes its parental shape. In some cases, the final product may require a coating treatment to provide additional insurance against chronic exposure to ultraviolet radiation or certain chemicals. For example, PC plastics cannot withstand contact with solvents such as benzene, acetone or sodium hypochlorite, otherwise known as the bleach for the household. Protective coatings also increase the surface resistance of products made of polycarbonate resin because they tend to be easily scratched.
The most common type of PC plastic is made by induction of resin polymerization by chemical reaction between phosgene isocyanates and bisphenol and (BPA) monomers. In fact, many common home products are made from BPA -based plastic from electronic and computer components afterBottles and containers for food storage. Because it is now known that BPA is an endocrine disruptor associated with infertility, congenital defects, neurological disorders and cancer -dependent cancer, its impact on human health for more than half a century is a great concern and continued use. Yet, despite numerous international studies and reports on this topic, very few countries were considering banning or modifying the use of BPA in the plastic industry. In 2009, however, Denmark moved to disable the use of BPA in children's bottles, and several US states independently banned their integration into all repeatedly applicable food and beverage containers, as well as those depositing infant nutrition and food.
