We supply the following Rubber Compounds:
- Natural Rubber (NR)
- Styrene-Butadiene Copolymer (SBR)
- Polybutadiene (BR)
- Iso-butylene-Isoprene Copolymer (IIR, CIIR, BIIR)
- Ethylene-Pr-opylene-Diene-Monomer (EPDM)
- Polychloroprene (CR)
- Acrylonitrile-Butadiene Copolymer (NBR, HNBR)
- Chlorosulfonated Polyethylene (CSM)
- Fluoroelastomer (FKM)
- Polyacrylate rubber (ACM)
- Epi-chlorohydrin rubber (ECO)
- Silicone rubber (VMQ)
Key Properties of BR
1. High Resilience:
- Rebound elasticity up to 70–80%, reducing heat buildup in dynamic applications.
2. Low-Temperature Flexibility:
- Glass transition temperature (Tg) as low as -100°C, ideal for arctic or winter conditions.
3. Abrasion Resistance:
- Superior to natural rubber (NR) and SBR, making it critical for tire treads.
4. Chemical Resistance:
- Poor resistance to oils, fuels, and ozone; primarily used in non-oil-exposed environments.
5. Tensile Strength:
- Moderate (15–20 MPa), improved by blending with NR or SBR.
Industry Applications
1. Tire Manufacturing:
- Tire treads (30–40% of BR consumption): Enhances wear resistance and grip.
- Sidewalls: Improves flex fatigue resistance.
- Winter/snow tires: Leverages low-Tg flexibility.
2. Industrial Products:
- Conveyor belts, hoses, and golf ball cores (high resilience).
3. Consumer Goods:
- Footwear soles, elastic bands, and sporting goods.
4. Blends:
- BR/NR: Balances resilience and tear strength for tire carcasses.
- BR/SBR: Optimizes cost and performance for all-season tires.
