SABIC® BR 4610 is a high cis-1,4 polybutadiene rubber stabilized with a non-staining antioxidant. SABIC® BR 4610 is manufactured by solution polymerization process using stereo-specific nickel catalyst system to control microstructure and molecular weight distribution and provides a highly linear polymer.

SABIC® EPDM 657 is a medium mooney viscosity, high ethylene and medium ENB content grade produced by solution polymerization using metallocene catalyst. It has medium molecular weight distribution with precise control of molecular composition and architecture. This product is available in pellet form.
