Styrene Butadiene Rubber Description and Usage
Performance
SBR-1500 is the most typical type of general-purpose contaminated soft styrene-butadiene rubber. The adhesiveness and processing properties of raw rubber are excellent. The wear resistance, tensile strength, tear strength and aging resistance of vulcanized rubber are better. SBR-1502 is the most typical type of general non-polluting soft styrene butadiene rubber. Its performance is equivalent to that of SBR-1500. It has good tensile strength, wear resistance and flexural energy.
Usage
Our high-quality bulk SBR is a versatile synthetic rubber widely used in:
-
Tire Industry: Essential for passenger car tires, truck tires, and specialty tires due to its excellent abrasion resistance and good aging properties.
-
Footwear Manufacturing: Used in shoe soles and other components requiring durability and flexibility.
-
Rubber Products: Conveyor belts, hoses, gaskets, seals, automotive parts, and various molded/extruded rubber goods.
-
Adhesives & Sealants: As a base polymer for certain adhesive and sealant formulations.

Styrene Butadiene Rubber Package and Storage
The inner packaging is a polyethylene film, and the outer packaging is a polypropylene coated woven bag. The net weight of each bag is 35±0.5kg. Store in a dry, ventilated, clean, and low temperature and room temperature warehouse. Avoid contamination, rain, flooding and direct sunlight when storing. During transportation, it should not be exposed to the sun, and should not be mixed with debris; it should not be stacked with flammable or oily materials. The transport car should be kept clean to avoid damage to the packaging and the intrusion of debris. The car should be covered with a rainproof cloth.
