Styrene Butadiene Rubber

(SBR) is a synthetic rubber copolymer that is widely used in various applications. It is made by the polymerization of two monomers, styrene and butadiene, and it can be produced in different ratios of these two components to achieve various properties. SBR is known for its durability, flexibility, and resistance to abrasion and heat. Here are some key characteristics and applications of SBR.

Characteristics of SBR:


SBR can be formulated to have different properties, such as oil resistance, abrasion resistance, and heat resistance, depending on the specific application requirements.


It is known for its excellent wear and abrasion resistance, making it suitable for applications that require long-lasting rubber components.


SBR is generally more cost-effective than some other synthetic rubbers, which makes it a popular choice for a wide range of applications.

Tensile Strength:

SBR has good tensile strength and can withstand stretching and bending without breaking easily.

Weather Resistance:

While not as weather resistant as some other rubber types like EPDM (Ethylene Propylene Diene Monomer), SBR can still withstand moderate exposure to outdoor elements.

Common Uses
of SBR:

Belts and Conveyor Systems
Gaskets and Seals
Hoses and Tubing
Foam Products

It’s important to note that there are different types of SBR with varying properties, so the specific formulation of SBR can be tailored to suit the requirements of a particular application.
