Butadiene Rubber UBEPOL VCR® (composite of rubber and resin)

Outline

UBEPOL VCR® is the grade that combines BR and high-crystalline syndiotactic polybutadiene (SPB) resin. SPB resin is well dispersed in BR matrix (Figure: TEM images). UBEPOL VCR®, having characteristic polymer alloy structure, can contribute to improve hardness, elastic modulus, crack growth resistance, and extrusion characteristics (extrusion output and dimensional stability) and weight reduction/thinning of rubber products.
