Processing aids for rubber compounding

Abstract

This paper reviews some aspects of rubber-filler interaction in the presence of resins. Laboratory investigations conducted by us with optical methods, power traces. DTA , DSC curyes and treatment of samples with various solvents and tests for physico-mechanical properties were used to demonstrate specificity in behaviour of selected resins and to discuss a concept which could explain mechanism of reinforcement in the presence of various resins, intimate analysis has snown capability of certain resin to promote wetting properties and give high true contact between iubber and carbon black particles, thereby best owing favourable physicc-mechanical properties to the compound. Information of this type can assist not only the compounders bat also can give theoretical explanation about additional reinforcement in the presence of selected resins.
