POLYBOND™ 3002

Low functionality and high viscosity maleic anhydride modified polypropylene coupling agent, ideal for use with processing equipment that does not have low feed rate capability.
Product Overview
POLYBOND™ 3002 is a coupling agent for glass fiber, cellulose fiber, or mineral-fillled polypropylene. It compatibilizes blends of recycled polypropylene/polyamide and polypropylene/EVOH to improve processing, mechanical properties, and long-term heat aging resistance.
