Styrene Butadiene Rubber (SBR), with the CAS number 9003 - 55 - 8, is a synthetic rubber that is produced by the copolymerization of styrene and butadiene. Our High - Quality Styrene Butadiene Rubber offers remarkable properties that make it highly sought after in various industries.
**Physical Properties**: It has a good balance of hardness, elasticity, and abrasion resistance. The density typically ranges from 0.91 - 0.94 g/cm³. Its glass transition temperature is around - 50°C to - 60°C, which allows it to maintain flexibility at low temperatures.
**Chemical Properties**: SBR is resistant to many chemicals, including non - polar solvents. It has a good resistance to oxidation and ozone attack, especially when proper antioxidants are added during the manufacturing process.
**Purity**: Our product has a high purity level, ensuring consistent performance in different applications. The styrene content in our SBR can be adjusted according to specific customer requirements, usually ranging from 20% - 40%.
Styrene Butadiene Rubber has a wide range of applications due to its excellent properties:
**Tire Industry**: It is the most common use of SBR. SBR is used in tire treads, sidewalls, and other tire components. Its good abrasion resistance and traction properties make it suitable for improving the durability and performance of tires.
**Footwear Industry**: SBR is used in the soles of shoes. It provides good shock absorption, slip - resistance, and flexibility, making it ideal for various types of footwear, including sports shoes, casual shoes, and work boots.
**Adhesive Industry**: SBR - based adhesives are used in many applications, such as in the bonding of rubber, leather, and fabric. These adhesives offer good bonding strength and flexibility.
**Coating Industry**: SBR can be used in water - based coatings for various substrates, such as concrete, metal, and wood. It provides good weather resistance and durability to the coatings.
**Processing**: SBR can be processed using various methods, such as extrusion, injection molding, and calendering. Before processing, it is recommended to pre - heat the SBR to improve its flowability. The processing temperature should be carefully controlled to avoid thermal degradation.
**Mixing**: When using SBR, it often needs to be mixed with other additives, such as fillers, plasticizers, and vulcanizing agents. The mixing process should be carried out evenly to ensure the uniform distribution of these additives in the SBR matrix.
**Vulcanization**: Vulcanization is an important step in the use of SBR. It cross - links the polymer chains, improving the mechanical properties of the rubber. The vulcanization process should be carried out under appropriate temperature and time conditions, depending on the type of vulcanizing agent used.
**Tire Manufacturing Case**: A tire company was facing challenges in improving the durability and traction of their tires. They decided to use our high - quality SBR in the tire treads. After replacing a portion of the natural rubber with SBR, they noticed a significant improvement in the abrasion resistance of the tires. The test results showed that the tires had a longer service life and better traction on wet and dry roads. The company was able to increase their customer satisfaction and market share.
**Footwear Manufacturing Case**: A footwear manufacturer wanted to develop a new line of sports shoes with better shock absorption and slip - resistance. They used our SBR in the soles of the shoes. The SBR provided excellent shock - absorbing properties, which reduced the stress on the wearer's feet during physical activities. The slip - resistance of the soles also met the industry standards, making the shoes safer for use on different surfaces. The new line of sports shoes was well - received in the market and led to an increase in sales for the manufacturer.
