1. 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.

2. 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.

The Features of UBEPOL BR? and UBEPOL VCR? for Rubber Applications

Product name		Mooney viscosity (ML1 4, 100°C )	Cis-1,4 content (wt%)	Characteristics
UBEPOL BR?	150	43	98	Standard grade. Superior balance of processability and physical properties.
	150B	40	97	High branching grade. Superior processability. Good open roll mill processability under high loading recipe
	130B	29	96	Low Mooney viscosity type of 150B. Superior processability. Most suitable for high loading of carbon black.
	150L	43	98	Low branching grade. Superior physical properties; Excellent abrasion resistance, resilience and heat build-up.

UBEPOL VCR?	412	45	98*	Standard grade of UBEPOL VCR? Superior extrusion and mill characteristics. Easily enhance hardness and modulus.
	617	62	98*	Special grade of UBEPOL VCR?. Superior processability than VCR412 Higher hardness and modulus than VCR412.
	450	39	98*	Broad molecular weight distribution type(Matrix BR). Good balanced between characteristics of VCR and the physical properties of general BR.
	800	40	98*	Broad molecular weight distribution type(Matrix BR). Improve extrusion characteristics of VCR450.
