Ningming Rosin

　　Rosin is a natural resin derived from renewable forest resources—the resin secreted by pine trees. Chemically, pine resin is a solution in which resin acids are dissolved in terpenes. After processing, pine resin can yield rosin (primarily composed of resin acids) and turpentine (primarily composed of terpenes). The global annual production of rosin is approximately

　　1.1 to 1.2 million tons, while the production of turpentine is around 250,000 tons. Currently, most of China’s rosin is directly used in the production of papermaking, paints, soaps, and inks. Due to its disadvantages such as easy oxidation and low softening point, the paint industry often converts the carboxyl groups of resin acids into resinates and resin acids esters for further use. The synthetic rubber and ink industries, on the other hand, utilize the double bonds of resin acids to produce disproportionated rosin, polymerized rosin, and hydrogenated rosin for reuse.

　　Currently, the domestic annual demand for resin and terpineol products reaches around 150,000 tons, with a shortfall of 12,000 tons. With the rapid development of domestic industries such as paints and printing, the demand for resin and terpineol in the domestic market is expected to rise significantly over the next 3 to 5 years.

　　Ningming County has a total of 1.5 million mu of Tungmian Pine forest, yielding 35,000 tons of pine resin annually, and holds broad market development potential. Domestic and international investors are welcome to invest in deep-processing projects of rosin in Ningming.
