The sources of rosin are mainly divided into three categories: resin rosin, wood rosin and floating oil rosin, in which resin rosin is collected and reprocessed in the form of picking and cutting, which is called rosin, which is characterized by the continuous harvesting of pine trees is conducive to the full use of resources. China is rich in resin resources, which has the largest output of resin rosin, and the output of resin rosin will remain more than 350000 tons for a long time. Wood rosin is a kind of rosin produced by chopping pine roots or trunks and extracting resin with solvent. It is mainly produced in the United States, and its raw materials depend on the primitive pine forests in the southeast of the country. Now, due to the shortage of forest resources, the output of wood rosin has dropped from 316000 tons in 1950 to 20, 000 tons now. The oil slick rosin comes from the wood pulp and paper industry, and the black liquor from Kraft pulping is processed, but its performance is not as good as that of resin rosin, but its performance is similar to that of resin rosin due to the continuous improvement of quality.

Summary: the above is about the rosin toxic and the price of the relevant introduction, it should be noted that the above rosin price only as a reference, the specific price should be based on the actual price, hope to help friends in need!
