Some trees secretions often forming resin, but amber is fossil resin, shellac resin although it is seen, but it is the secretion of the lac insect deposits in the trees. Shellac is made from shellac, initially only used as a wood preservative, but with the invention of the motor insulation paint has become the first use. However, after the 20th century, natural products have been unable to meet the needs of electrification, prompting people to have to find new cheap substitutes. Bakelite by the advent of WB-50 resin manufacturers soon discovered that it not only can create a variety of electrical insulation products, but also the system daily, Edison (T.Edison) for the manufacture of recordings, and soon claimed in the ad: Already with Bakelite thousands of products made out of 802 resin, so one time hailed the Baekeland's invention of the 20th century "alchemy." Coal tar as the original grain of phenolic resin 801 resin, in 1940 has been among the first of a variety of synthetic resin production, up to 20 million tons per year, but then with the development of the petrochemical and polymer synthetic resins such as: Poly ethylene and polystyrene production also expanded with the establishment of many of these products more than 100,000 tons annual output of large plants, they have become today's most productive four synthetic resin. Synthetic resin plus additives by various molding methods to obtain plastic, the plastic today there are dozens of varieties, the world's annual production of about 120 million tons, China is also more than 5 million tons, they have become the production and living basic materials and national defense construction.
