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.

Cosmetics Industry

The residue left after the distillation of the volatile oil of oleoresin obtained from Pinus palustris and other species of Pinaceae. It is less and less used in cosmetics for the benefit of its esters, in cosmetics. It is authorized in Bio.

Adhesive Agent

Rosin, or more correctly rosin acid, is one of the oldest raw materials for the adhesives industry, either as such or converted to derivatives. Three sources of rosin are used for resin manufacture, gum rosin, wood rosin and tall oil rosin, all generated from the pine tree.

Pulp and Paper Industry

Rosin is added to paper pulp to increase resistance to water and other liquids. Alum (short for aluminum sulfate) is added to help the rosin adhere to the paper fibers.

Paint and Coating Material

It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperatures. It chiefly consists of different resin acids, especially abietic acid.
