Gum Rosin Grade X (Gum Rosin)

Brief Overview

Gum Rosin (GR) is product consisting essentially of a mixture of gum and resin usually obtained by making an incision in a plant and allowing the juice which exudes to solidify. GR also is a nonvolatile component of crude gum which is included largely in plants belonging to pine family (Pinaceae). It mainly consists of a various isomer technically called resin acids.

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.
