Frequently Asked Questions
Applications of Styrene-butadiene rubber 1721
Styrene-butadiene rubber (SBR) 1721 is a type of synthetic rubber that is widely used in various applications due to its excellent properties and versatility. Some of the common applications of SBR 1721 include:
1. Tires: SBR 1721 is extensively used in the manufacturing of tires, where it is blended with natural rubber (NR) or other types of synthetic rubber. It helps improve the abrasion resistance, grip, and overall performance of the tire tread.
2. Automotive components: SBR 1721 is used in the production of various automotive components such as seals, gaskets, hoses, belts, and vibration dampeners. Its high durability, resistance to oils and chemicals, and good mechanical properties make it suitable for these applications.
3. Footwear: SBR 1721 is commonly used in the production of footwear, including athletic shoes, sandals, and boots. It provides good flexibility, abrasion resistance, and water resistance, making it suitable for different types of footwear.
4. Conveyor belts: SBR 1721 is employed in the manufacturing of conveyor belts due to its excellent abrasion resistance, tensile strength, and durability. These properties allow conveyor belts to withstand heavy loads, high speeds, and harsh environments.
5. Adhesives and sealants: SBR 1721 is used as a binder in the production of adhesives and sealants. It provides good adhesion to various substrates, including metal, rubber, and plastic, making it suitable for applications such as bonding in construction, automotive, and general industrial sectors.
6. Foam products: SBR 1721 can be foamed to produce materials with cushioning and insulation properties. It is used in the production of foam products like padding, mattresses, upholstery, and packaging materials.
7. Coatings and paints: SBR 1721 is incorporated into coatings and paints to enhance their flexibility, adhesion, and durability. It is used in applications where resistance to weathering, chemicals, and abrasion is required.
8. Electrical insulation: SBR 1721 is employed in the production of electrical cables and wires as an insulating material. Its excellent dielectric properties make it suitable for this application.
These are just a few examples of the many applications of SBR 1721. Its versatility, affordability, and desirable properties have made it a popular choice in various industries.
