Styrene Butadiene Rubber 1502

Description of Styrene Butadiene Rubber 1502

SBR 1502 is a cold polymerized styrene-butadiene rubber (SBR) that stands out for its exceptional performance in various applications.

Characterized by its excellent tensile strength, abrasion resistance, flexibility, and recovery properties.
SBR 1502 is a popular choice for the manufacturing of tires, footwear, mechanical goods, and other rubber-based products.
The “1502” designation is indicative of specific characteristics and properties of the rubber, including its styrene content and polymerization method.

Cold polymerization, opposite to hot polymerization, results in a rubber with enhanced properties, such as lower heat build-up and improved resistance to degradation.
The precise composition and processing of SBR 1502 contribute to its versatility and suitability for a wide range of applications.

Applications of Styrene Butadiene Rubber 1502

It is general-purpose rubber. Whatever it is widely used in tire, rubber technical, shoe, cable, and other industries for the production of automobile tires and tubes, a wide assortment of rubber technical articles, white and color shoes, cable and children’s toys castings, and so on.

Why is SBR 1502 used to make car tires?

In general, there are a number of key reasons why SBR 1502 can be used in the manufacture of car tires, including:

Abrasion and wear resistance

this property of SBR 1502 will make it indispensable for use in tires as long as durability and longevity can be achieved in such tires. In this way, the tires can resist adverse road conditions and last longer.

Balance of strength and flexibility of Styrene Butadiene Rubber 1502

SBR offers a good balance between tensile strength and flexibility.

It is tough enough to provide durability for the tires, yet flexible enough to absorb shocks and vibrations for better comfort.

Value for money

SBR is cheaper than natural rubber and hence cost-effective for the manufacturers to use in tire production without compromising the performance.

Heat Resistance of SBR

The tires of cars are expected to bear high temperatures, especially in continuous driving.  SBR 1502 has good heat resistance, which prevents degradation of tires under such conditions.

Compatibility with Other Materials

Most of the time, SBR is blended with other types of rubber in tire formulations, such as natural rubber and butadiene rubber, allowing manufacturers to fine-tune properties for specific performance needs.

Good traction on wet surfaces of SBR 1502

Styrene Butadiene Rubber 1502 contributes to the performance of the tire on a wet road by bringing in a good balance between grip and rolling resistance for improved safety and fuel efficiency.

SBR 1502 Properties

Styrene Butadiene Rubber 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.

Styrene Butadiene Rubber 1502 Packing

SBR 1502 Packing

Styrene Butadiene Rubber (SBR) 1502 is typically packed in bales or slabs.

Bales are large, compressed bundles of the rubber. while slabs are flat, rectangular blocks.

The choice between bales and slabs often depends on the desired quantity, transportation methods, and storage conditions.

Both methods provide effective protection such as wrapped in plastics for the rubber during storage and transportation, ensuring its quality and integrity.
