INTRODUCTION

Indorez® Coumarone Indene Resin also known as CI Resin, is a thermoplastic aromatic resin which is produced through the polymerization of coumarone, indene & styrene. Each of these three ingredients  play an important role in the performance of CI resin. Coumarone imparts cohesiveness and works as process aid, Styrene imparts heat resistance and Indene imparts transparency and better adhesiveness.

Coumarone Indene Resin has very good affinity with natural and synthetic rubbers. Its key characteristics include imparting good performance as a tackifier, softening and reinforcing agent.

These type of resins are designed to have excellent resistance to alkalis, dilute acids and moisture. They can improve the moulding operation, increase the hardness and elasticity of the product.
