SBR 1502

SBR 1502 is a cold polymerized, 23.5% styrene SBR polymer made with a mixed-acid emulsifier, non- staining stabilizer, and salt-acid coagulation. SBR 1502 exhibits the excellent tensile strength, abrasion resistance, flexibility and recovery properties, it's also one of the most frequently-used synthetic rubber in rubber industries.

SBR 1502 in Tire Production

Synthetic rubber is a crucial material in tire production and is widely used in the manufacturing of various tire components. Synthetic rubber, as opposed to natural rubber, offers several advantages such as enhanced durability, consistent quality, and improved performance characteristics.

Here are some key areas where synthetic rubber products are utilized in tire production:

  1. Tread Compound: The tread is the outermost part of the tire that comes into contact with the road. It is responsible for providing traction, grip, and wear resistance. Synthetic rubber, such as styrene-butadiene rubber (SBR) or polybutadiene rubber (BR), is commonly used in the tread compound due to its excellent wear resistance and grip properties.

  2. Sidewalls: The sidewalls of a tire provide structural support and protection. Synthetic rubber is used in the formulation of sidewall compounds to provide strength, flexibility, and resistance to cracking and aging.

  3. Bead Filler: The bead is the part of the tire that anchors it to the rim. Synthetic rubber is often used as a bead filler material to ensure proper seating and stability of the tire on the rim.

  4. Inner Liner: The inner liner is a layer inside the tire that acts as an airtight barrier. It helps maintain tire inflation and prevents air leakage. Synthetic rubber, particularly halobutyl rubber, is commonly used as an inner liner material due to its impermeability to air and moisture.

  5. Belt Reinforcement: In radial tires, layers of fabric cords or steel belts are used for reinforcement. Synthetic rubber is often used as a bonding agent or adhesive to provide strong adhesion between the rubber and the reinforcement materials.

  6. Other Components: Synthetic rubber may also be used in other tire components such as the chafer (located at the bead edge for protection), cushion gum (between the plies and the sidewall), and other specialized parts that require specific properties.

SBR 1502 Properties

SBR 1502 is one of the SBR rubber products known for its excellent abrasion resistance, high tensile strength, and flexibility. It exhibits moderate weather and water resistance, making it suitable for indoor and outdoor applications. With low heat buildup and good electrical insulation properties, it finds use in automotive tires, conveyor belts, gaskets, and molded rubber goods. Cost-effective and compatible with various fillers, SBR 1502 is a versatile choice for a wide range of industrial applications.

Application of SBR 1502

SBR 1502 can be used for tire, light colored transparent sole, rubber cloth, light fitness equipment, flooring and other industrial rubber products.
