What you don't know about BPA

BPA is an industrial chemical that can enter your food and drink.
BPA, known as 2,2-II (4-hydroxyl) propane, or biphenol propane for short. White crystals, melting point 156 to 158 degrees C

. Mainly used in the preparation of epoxy resins (about 65%) and polycarbonate (about 35%), potassium salts or sodium salts are the raw material for the production of polyrulum, a small amount used as rubber anti-agering agents (see rubber additives).

BPA is an important organic chemical raw material, an important derivative of phenol and acetone, mainly used in the production of polycarbonate, epoxy resin, polyester resin, polyphenyl ether resin and other polymeric materials. Can also be used in plasticizers, flame retardants, antioxidants, thermal stabilizers, rubber anti-aged agents, pesticides, coatings and other fine chemical products.
been used since the 1960s to make plastic (milk) bottles, suction cups for young children, and inside coatings in food and beverage (milk powder) cans. BPA is everywhere, from mineral water bottles and medical devices to food packaging. Every year, 27 million tons of plastic containing BPA are produced worldwide. But BPA can also lead to endocrine disorders that threaten the health of fetuses and children. Obesity caused by cancer and metabolic disorders is also thought to be linked. The European Union considers BPA-containing bottles to induce precociousness, and on 2 March 2011 banned the production of baby bottles containing the chemical BPA.
BPA is mainly used in the production of epoxy resin, polycarbonate, is currently one of the fastest growing demand in China's chemical products, the main use in China is the preparation of epoxy resin. Historically, Chinese epoxy manufacturers produced their own BPA, which was not available on the market at the time. After the reform and opening up, users of epoxy resin quality, varieties have high requirements, when Wuxi resin factory, Shanghai resin factory has launched bPA production process research. In order to eliminate the long-standing sulphuric acid production of BPA process, since the early 1980s, China Wuxi resin plant, Shanghai dyeing plant, Dalian paint factory almost simultaneously carried out the test work of ion law BPA, but also want to learn from foreign advanced experience, plans to introduce BPA advanced technology to develop China's BPA, but both of these road forward have encountered difficulties. According to China Epoxy Industry Association expert Cha Wenhai introduced: the former in the 500 tons / year of industrial testing, encountered after-treatment equipment, technology can not pass the problem; Under such circumstances, Wuxi resin factory in the late 1980s from Poland introduced a more advanced ion method to produce BPA technology, narrowing the gap with the world's advanced level, solve the development of epoxy resin encountered in the raw material difficulties, so that domestic epoxy resin in the fierce market competition to win a place.
