Styrene Butadiene Rubber/ SBR Industrial Grade CAS 9003-55-8

 

Description:
Styrene Butadiene Rubber (SBR) is a copolymer of styrene and butadiene. It is created through the polymerization of these two monomers. SBR is a versatile rubber material that exhibits good mechanical properties, such as high tensile strength, abrasion resistance, and resilience.

Specification:
The specifications of Styrene Butadiene Rubber can vary depending on the specific grade and application. Here are some general specifications:

• Chemical formula: (C8H8)x(C4H6)y
• Appearance: Generally, SBR is a milky white to light yellow solid, but it can also be produced in liquid form.
• Mooney viscosity: Typically, 30-90 Mooney units (measurement of rubber viscosity)
• Styrene content: Generally ranges from 20% to 30% by weight
• Bound styrene: Typically, 20% to 50% by weight
• Bound butadiene: Typically, 50% to 80% by weight
• Glass transition temperature (Tg): Approximately -50 to -60 °C
• Polymerization method: Emulsion polymerization or solution polymerization

Application:
Styrene Butadiene Rubber (SBR) finds widespread application in various industries, including:

1. Tires: SBR is one of the primary materials used in the production of automobile tires. It provides excellent wear resistance, high grip, and good rolling resistance, making it suitable for both passenger and commercial vehicle tires.

2. Footwear: SBR is used in the manufacturing of shoe soles, heels, and other footwear components. It offers durability, abrasion resistance, and flexibility, making it ideal for different types of footwear.

3. Conveyor belts: SBR is employed in the production of conveyor belts due to its high tensile strength, good abrasion resistance, and low rolling resistance. It helps deliver efficient and reliable transport of materials in industries such as mining, logistics, and manufacturing.

4. Industrial rubber goods: SBR is utilized in various industrial rubber goods, including hoses, seals, gaskets, O-rings, and industrial rubber sheets. Its mechanical properties and resistance to abrasion make it suitable for these applications.

5. Adhesives and sealants: SBR is often used as a base polymer in the formulation of adhesives and sealants. It provides good adhesion to various substrates, flexibility, and resistance to aging.

6. Automotive components: SBR is employed in the production of automotive components such as engine mounts, grommets, bushings, and rubber vibration isolators. Its properties help reduce vibrations, noise, and provide effective damping.

Features:

1. Good mechanical properties: SBR exhibits high tensile strength, good tear resistance, and resilience, making it suitable for applications that require durability and toughness.

2. Excellent abrasion resistance: SBR has good resistance to abrasion and wear, making it an ideal choice for applications that involve contact with rough surfaces or repetitive mechanical stress.

3. Low cost: SBR is relatively cost-effective compared to other synthetic rubber materials, making it a popular choice in various industries.

4. Weather and ozone resistance: SBR offers moderate resistance to weathering and ozone exposure, allowing it to withstand outdoor applications reasonably well.

5. Processability: SBR can be easily processed using conventional rubber processing methods such as extrusion, molding, and calendaring.
