Extraction of lignin from sawdust for rubber compounding

Abstract

The increasingly stringent requirements of rubber product consuming industries have put demand on Sri Lankan rubber processing industry to provide rubber parts with better performance such as high tensile strength, good tear resistance and low abrasion. The economic recession and competition from abroad are other major challenges facing Sri Lankan rubber industry. To satisfy customer needs and meet competition local rubber industrialists have to realize the importance in basic research and their investment, Special attention is to be brought to upgrade and develop rubber formulation technologies based on cheap and locally available raw materials.
