UBEPOL BR? (high-cis BR)
UBEPOL BR? has attractive grades with superior physical properties such as abrasion resistance, rebound, tensile strength, heat build up, and grades with excellent processability such as mixing, roll banding, extrusion.

UBEPOL VCR? (composite of rubber and resin)
UBEPOL VCR? consists of high-cis BR and high-crystalline syndiotactic polybutadiene resin which is a special type of polymer alloy.
UBEPOL VCR? can contribute to produce various advantages;

to increase hardness, modulus of rubber product without adding filler.

to reduce the volume or weight of rubber product by utilizing its reinforcing effect.

to improve extrusion properties (extrusion output and dimensional stability) and roll mill shrinkage.
