Brief Overview
This is a resin obtained by copolymerization of the renewable material terpene monomer and phenol. By altering the phenol modification degree for each grade, we offer grades that are compatible with low to high polarity materials.
Manufacturing Process
Production of TPR is by the controlled treatment of the monomer in solution in a hydrocarbon diluent with a catalyst such as anhydrous aluminium chloride, of the Friedel-Crafts type. As the polymerization reaction is highly exothermic, provision must be made for adequate agitation and heat exchange. Upon the completion of the reaction, removal of unreacted terpenes, solvent and any low-terpene polymers are done by mixture with low pressure steam. The residual nonvolatile molten TPR is then poured into drums to cool or used in the preparation of resin solutions.
