Custom SBR Products
Styrene-Butadiene Rubber (SBR) is a synthetic copolymer of styrene and butadiene, designed to replicate and enhance many of the properties of Natural Rubber while offering improved processability, heat resistance, and aging stability. Developed as one of the most versatile and cost-effective elastomers, SBR combines consistent performance, good mechanical strength, and excellent abrasion resistance — making it the most widely used synthetic rubber globally.
At Eutsler Technical Products, our SBR compounds are custom formulated to achieve reliable performance in industrial, automotive, and mechanical applications, where resilience, flexibility, and durability are required under moderate environmental exposure. SBR maintains high elasticity, low hysteresis, and excellent wear characteristics, providing consistent compression and sealing performance in dynamic and static service.
Performance Advantages
- Excellent abrasion and wear resistance performs exceptionally in sliding, impact, and rolling contact applications.
- Good mechanical strength and resilience retains elasticity and shape under repetitive loading.
- Cost-effective and consistent quality stable polymer structure ensures batch-to-batch consistency.
- Good impact and shock absorption suitable for vibration isolators, pads, and suspension components.
- Improved heat and aging resistance over Natural Rubber when properly formulated.
- Compatible with fillers and reinforcing agents for tailored physical properties.
Applications
Eutsler designs and molds SBR-based elastomer components for a wide range of uses across industrial, automotive, and general mechanical systems.
Typical applications include:
- Vibration isolators and shock mounts
- Roll coverings and conveyor elements
- Gaskets, seals, and diaphragms (non-oil environments)
- Tires and wear surfaces
- Flooring and protective pads
- Bushings, dampers, and flexible couplings
- Rubber-to-metal bonded components
SBR’s balanced performance and economic value make it a preferred choice for medium-duty dynamic and static sealing applications where oil resistance is not a requirement.
Superior Material Performance
Eutsler’s SBR compounds deliver:
- Tensile strength up to 3,000 psi with good elongation
- High resilience and recovery for dynamic vibration service
- Excellent abrasion and tear resistance
- Good compression set behavior under sustained load
- Stable mechanical and dynamic response across wide hardness range (40–90 Shore A)
- Good flexibility and low-temperature performance down to –60 °F (–50 °C)
Note: SBR is not oil- or fuel-resistant and requires antiozonant and antioxidant protection for prolonged outdoor exposure.
General Characteristics of SBR Elastomer
| Property | Typical Range / Rating | Comments |
|---|---|---|
| Durometer Range (Shore A) | 40 – 95 | Broad hardness range for dynamic and static seals |
| Tensile Strength (psi) | 1,000 – 3,000 | Moderate to good mechanical strength |
| Elongation at Break (%) | 250 – 600 | High flexibility and toughness |
| Compression Set | Good | Retains load under cyclic pressure |
| Resilience / Rebound | Good | Balanced elasticity; moderate damping |
| Abrasion Resistance | Excellent | Ideal for high-friction or rolling surfaces |
| Tear Resistance | Good | Durable under repeated flexing |
| Oil Resistance | Poor | Not suitable for hydrocarbon oils or fuels |
| Solvent Resistance | Limited | Compatible with water, alcohols, and glycols |
| Low-Temperature Usage | –60 °F (–50 °C) | Retains flexibility in cold environments |
| High-Temperature Usage | +225 °F (105 °C) | Stable under moderate heat |
| Weather / Ozone / Sunlight Resistance | Fair | Antioxidant and antiozonant protection recommended |
| Adhesion to Metals | Good | Bonds well with proper surface treatment |
