The rosin abietic acid molecule can be manipulated in many ways to give tailored properties, including specific color, thermal and oxidative stability, softening point, reactivity, and solubility characteristics. The Eastman family of rosin resins now includes rosins and modified rosin resins, rosin esters, polymerized rosin esters, acid-modified rosin esters, liquid resins and dark rosins. These products, ranging in color from light yellow to dark brown, have many Food and Drug Administration clearances for food contact. Rosin and Modified Rosin Resins Eastman rosins and modified rosin resins are broadly compatible with natural and synthetic elastomers, polymer and copolymer thermoplastics, cellulose derivatives, thermosetting resins and a variety of oils, resins and waxes. They are soluble in aliphatics, aromatics, esters, ketones, alcohols, ink oils and chlorinated hydrocarbons.
Soaps also are products in the rosin and modified rosin resin line.
Soaps are used to modify rubber and plastics compounds and in asphalt and cement mixtures. Soaps include Dresinate . Hercules , Poly-Pale , Dymerex , Pamite and Dresinate are registered trademarks of Hercules Incorporated. They have FDA clearance for a wide range of food contact and food ingredient applications. They are soluble in aromatics, esters, ketones, alcohols, ink oils and chlorinated hydrocarbons and are partially soluble in aliphatics.
