Gum Rosin Grade M - China

Briev Overview
Gum rosin Grade M is a specific classification of gum rosin, a natural resin obtained from pine trees. Gum rosin is produced through the extraction of resin from the pine tree's living tissues, primarily the oleoresin ducts. The Grade M designation indicates a certain quality or specification within the gum rosin category.
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.
