Nitrile Butadiene Rubber (NBR) – Rolled Grade V

This grade is engineered specifically for industrial environments requiring high resistance to petroleum-based oils, fuels, and chemical solvents. It serves as the primary compounding base for manufacturing heavy-duty fuel and oil hoses, automotive O-rings, hydraulic seals, and industrial gaskets. Its excellent mechanical strength ensures long-term sealing integrity under mechanical stress.

Key Properties: Optimized with a Mooney Viscosity of 55 ($100^\circ\text{C}$) to balance processability and structural strength, maintaining low volatile matter ($\le 0.8\%$) and low ash content ($\le 0.5\%$).

Market Equivalent: Direct replacement for Sibur Nitrastab series (NBR 2655 / NBR 3355).

Isobutene-Isoprene Rubber (IIR) – Rolled Grade K

This grade is engineered specifically for industrial environments requiring high resistance to petroleum-based oils, fuels, and chemical solvents. It serves as the primary compounding base for manufacturing heavy-duty fuel and oil hoses, automotive O-rings, hydraulic seals, and industrial gaskets. Its excellent mechanical strength ensures long-term sealing integrity under mechanical stress.

Key Properties: Optimized with a Mooney Viscosity of 55 ($100^\circ\text{C}$) to balance processability and structural strength, maintaining low volatile matter ($\le 0.8\%$) and low ash content ($\le 0.5\%$).

Market Equivalent: Direct replacement for Sibur Nitrastab series (NBR 2655 / NBR 3355).

Butadiene Rubber (BR) – Rolled Grade B

This High-Cis Polybutadiene rubber is designed for compounds that demand extreme elasticity, high rebound resilience, and superior resistance to abrasive wear. Its dominant use is in tire tread compounding to improve wear resistance and reduce rolling resistance. It is also the standard choice for manufacturing heavy-duty conveyor belt covers, robust footwear soles, and high-impact mechanical rubber components.

  • Key Properties: Formulated with a Mooney Viscosity of 50 ($100^\circ\text{C}$) and tight plasticity limits (0.30–0.35) to ensure excellent filler dispersion during mixing.

  • Market Equivalent: Direct replacement for Sibur BR-1203 / SKD-ND.

Isoprene Rubber (IR) – Rolled Grade A

Serving as a high-purity synthetic alternative to Natural Rubber (NR), this cis-1,4-polyisoprene grade offers excellent tensile properties, high resilience, and low heat build-up. It is heavily utilized in high-stress tire components (such as sidewalls and carcasses), heavy-duty mechanical rubber goods (MRG), conveyor belts, and medical-grade rubber formulations where compounding consistency is critical.

  • Key Properties: Delivers a robust tensile strength ($\ge 30.4\text{ MPa}$) and high elongation at break ($\ge 800\%$) with a controlled Mooney Viscosity of 60.

  • Market Equivalent: Direct replacement for Sibur SKI-3.

Brominated Isobutylene-Isoprene Rubber (BIIR) – Rolled Grade K

As a specialized Bromobutyl elastomer, this product provides the ultimate gas barrier performance along with faster curing rates and better co-vulcanization with general-purpose rubbers. It is the global standard for manufacturing the inner liners of modern tubeless tires. Additionally, its high purity makes it ideal for pharmaceutical stoppers, medical packaging, and chemical tank linings.

  • Key Properties: Contains a precise bromine content of 1.5–2.2% with a Mooney Viscosity of 46.6 ($125^\circ\text{C}$), ensuring superior aging stability and clean molding.

  • Market Equivalent: Direct replacement for Sibur BBK-232 / BBK-239.

Chlorinated Isobutylene-Isoprene Rubber (CIIR) – Rolled Grade K

This Chlorobutyl grade combines the heat resistance and low gas permeability of butyl rubber with enhanced curing flexibility. It is highly preferred for heat-resistant industrial hoses, steam hoses, durable conveyor belts, and pharmaceutical vial closures. Its distinct chemistry allows it to maintain a stable cure profile even when blended with other elastomers.

  • Key Properties: Maintained at a Mooney Viscosity of 46.6 ($125^\circ\text{C}$) with a specified chlorine content of 1.1–1.4% and an ultra-low ash content ($\le 0.5\%$).

  • Market Equivalent: Direct replacement for Sibur CBK-139 / CBK-150.
