CAS No.:8050-09-7
application:
Suitable for paper making, coating, printing ink, rubber, soap, electronics, edible ester gum, rosin ester resin and other important industrial raw materials.
Features:
Rosin is obtained by cutting resin juice directly from the trunk of pine trees.A 13cm cut was made in the trunk of the grown pine tree to collect the colorless and fragrant viscous liquid that flowed from the tree. The liquid was distilled by steam vacuum. The distillate was turpentine, and the residue in the kettle was rosin.Rosin is characterized by light color, high acid value, high softening point, used for making washing soap, metal soap, varnish, ink, welding materials, insulating materials.

applications:
The special hot melt rubber, the Graft-Chloroprene Resin, the high-quality shoe sole adhesive, the Hot-melt coating, gravure printing ink and so on.
Features:
Terpene-phenolic resin 803L: Is a kind of rosin as raw material to produce the high softening point, light color, and good to focus on the terpene phenolic resin, especially suitable for the polymerization of chloroprene rubber adhesives, then applied to PVC artificial leather.Due to its good heat resistance, it has good solubility with various kinds of elastomers and resins and can prolong the maintenance time of solvent type adhesive.
