Technology Overview

Carboxylated Styrene-Butadiene Rubber Latex (XSBR) represents a significant advancement in synthetic latex technology. Manufactured through emulsion copolymerization of butadiene, styrene, and a carboxylic acid monomer, this innovative latex incorporates carboxyl functional groups that dramatically enhance adhesion, mechanical strength, and chemical resistance compared to conventional SBR latex.

XSBR is the preferred choice for applications demanding exceptional bonding strength, water resistance, and long-term durability across paper processing, carpet manufacturing, construction, and automotive industries.
