Gum Rosin<\/strong><\/b><\/p>\n

OTHER NAME:<\/strong><\/b>\u00a0\u00a0<\/strong><\/b>Rosin<\/p>\n

DESCRIPTION<\/strong><\/b><\/p>\n

Rosin is a natural resin. The raw material of rosin comes from the renewable pine forest resource – rosin in pine trees. From the chemical composition of rosin, it is a solution of resin acid dissolved in terpenes. After the rosin is distilled, a certain fraction is taken to obtain rosin.<\/p>\n

Classified according to the production process, the currently mainstream rosins produced in China are: steam-based resin rosin; According to the source of raw materials, the currently mainstream rosin produced in China is: gum rosin. Among them, the sources of rosin are divided into: masson pine rosin, wetland pine rosin, and simao pine rosin.<\/p>\n
