The copolymer's alternating styrene and butadiene blocks provide a balance of hardness and flexibility, respectively. The styrene blocks contribute rigidity and processability, while the butadiene blocks add rubber-like elasticity, ensuring that carpets remain resilient and comfortable underfoot.

In the carpet-making process, SBR latex is applied to the carpet's backing material, which is then bonded to the face fibers. The cohesive strength and tackiness of the SBR block copolymer ensure that this bond is strong and durable, preventing delamination and enhancing the carpet's overall structural integrity. The copolymer's ability to wet out fibers effectively further enhances adhesion, creating a seamless connection between the carpet's components.
