Pine Chemicals

SilicaStar supplies natural raw gum rosins as well as their derivatives. These products are widely used in ink and graphic arts, synthetic rubber, adhesives, paint and coatings, and paper making industries.

Gum Rosin

Gum Rosin is a natural organic product with resin acid as the main component. It is mainly used as raw material for the manufacturing of soap, paper, paint, rubber, ink, adhesive, electronic and intermediate for synthetic organic chemicals.

SilicaStar Industries provide both unmodified gum rosins and modified gum rosins.

SilicaStar Industries supply two types of unmodified gum rosins, Massoniana rosin and Elliottii rosin depending on the kinds of pine source where the oleoresin is exuded, Pinus Massoniana Lamb or Pinus Elliottii Engelm.

Modified Gum Rosin

SilicaStar Industries modified gum rosins can be used in coating, ink, and adhesive formulations.

Rosin Ester

SilicaStar Industries rosin esters are used in a wide range of applications including adhesives, sealants, and pressure sensitive adhesive tapes and labels. Maleic modified glycerine rosin resin (MALRES300) is designed for applications in ink and coating industries.

Pinus Massoniana & Pinus Elliottii Gum Rosins

SilicaStar Industries supply two types of gum rosins, Massoniana rosin and Elliottii rosin depending on the kinds of pine source from which the oleoresin is exuded, Pinus Massoniana Lamb or Pinus Elliottii Engelm. Pinus Massoniana Lamb is rich in alpha pinene, while Pinus Elliottii Engelm is rich in alpha pinene.

Alpha-pinene and beta-pinene are two isomeric terpenes which are the major components of gum rosin which can be obtained from the resinous sap of pine trees by steam distillation. Terpene is an unsaturated hydrocarbon whose carbon skeletons are built up from isopentyl (isoprene) C5 units, consisting of five carbon atoms attached to eight hydrogen atoms (C5H8). The alpha form boils at 155-156°C, and of the beta form boils at 165-168°C. It is used as solvents for paints, coatings and wax formulations. It is used as an intermediate for resins and for camphor, menthol, campholenic aldehyde and terpineol. It is used as lube-oil additives.

The physical properties comparison of alpha- and beta-pinene is as the follow:
