UBEPOL BR? (high-cis BR)
UBEPOL BR? has attractive grades with superior physicalproperties such as abrasion resistance, rebound, tensile strength,heat build up, and grades with excellent processability such asmixing, roll banding, extrusion.
UBEPOL VCR? (composite of rubber and resin)
UBEPOL VCR? consists of high-cis BR and high-crystallinesyndiotactic polybutadiene resin which is a special type of polymeralloy.
UBEPOL VCR? can contribute to produce various advantages;
to increase hardness, modulus of rubber product without addingfiller.
to reduce the volume or weight of rubber product by utilizingits reinforcing effect.
to improve extrusion properties (extrusion output anddimensional stability) and roll mill shrinkage.
