Sbr Latex Polymer Manufacturers In Hyderabad

What is SBR Latex?

SBR Latex stands for Styrene-Butadiene Rubber Latex. It is a synthetic rubber emulsion produced by the polymerization of styrene and butadiene in water. SBR latex is a milky white, viscous liquid and is widely used in construction, adhesives, coatings, and textiles due to its excellent adhesion, flexibility, water resistance, and durability.

🧪 Chemical Composition

Styrene (C₈H₈): Provides rigidity and strength

Butadiene (C₄H₆): Provides elasticity and flexibility

Typically stabilized with surfactants (like soaps or emulsifiers)
