Gum Rosin Grade WW - Vietnam

Brief Overview
Gum rosin, also known simply as rosin, is a natural resin obtained from pine trees, particularly species belonging to the genus Pinus. It is produced through the extraction of resin from the living pine trees, primarily by making incisions in the bark and collecting the exuded sap. The collected resin undergoes a process of distillation to separate impurities and obtain the purified gum rosin.
Manufacturing Process
Gum Rosin is produced from the crude pine resin collected from pine trees. The resin is subjected to distillation and the distillation process is carried out in large copper stills. The volatile liquid terpene components would separate from the mixture as it vaporizes at a temperature between 100 to 160°C, leaving behind fluid rosin as the distillate. This fluid rosin is collected and purified by passing it through straining wadding. The condensate left behind is called turpentine oil.
