Key Properties of SBR
1. Abrasion Resistance:
- Superior to natural rubber (NR), making it ideal for high-wear applications like tires.
2. Cost-Effectiveness:
- Lower production cost compared to NR and specialty rubbers like NBR or FKM.
3. Temperature Range:
- Standard grades: -50°C to 100°C; limited heat resistance compared to EPDM or silicone.
4. Elasticity and Tensile Strength:
- Moderate tensile strength (15–25 MPa), improved with fillers like carbon black.
5. Weather Resistance:
- Poor ozone and UV resistance unless blended with additives (e.g., antioxidants, waxes).
6. Oil/Fuel Resistance:
- Low; unsuitable for hydrocarbon-exposed environments.
Industry Applications
1. Tires:
- Tire treads and sidewalls (70% of SBR consumption), optimized for grip and wear.
- Solution SBR (S-SBR): High-performance tires with lower rolling resistance.
2. Footwear:
- Shoe soles due to abrasion resistance and cost efficiency.
3. Industrial Products:
- Conveyor belts, hoses, and gaskets (non-oil environments).
4. Adhesives and Coatings:
- Pressure-sensitive adhesives (e.g., tapes, labels) for strong tack.
5. Consumer Goods:
- Floor mats, rubber toys, and seals.
