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.
