Gum Rosin Grade N - China

Brief Overview
Gum rosin Grade N is a specific classification of gum rosin, which is a natural resin obtained from pine trees. The term "Grade N" typically refers to a specific quality or grade of gum rosin. Gum rosin itself is produced through the extraction of resin from pine trees, mainly pine species like Pinus elliottii and Pinus taeda.
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.
