Feature of Polybutadiene Rubber UBEPOL BR® 23H

Synthetic Rubber

Outline

UBEPOL BR® 23H is a original grade of UBE with bimodal molecular weight distribution. UBEPOL BR® used for HIPS offers well balanced properties : superior impact strength, stiffness, and so on. It is the most suitable for special use like flame retardant HIPS.

1. Molecular Weight Distribution

UBEPOL BR® is the original grade of UBE. Unlike 15H series, 23H has bimodal molecular weight distribution (Fig.1).
