High Solid SBR Latex – The Next Generation of Carpet Backing Performance

High Solid Styrene-Butadiene Latex, or HS-SBR, represents a major step forward in carpet manufacturing technology. With a solid content of up to 67 percent, this latex allows producers to achieve better productivity, stronger bonding, and lower energy consumption. The transition from conventional SBR to high solid latex is not just a change in formulation but a complete upgrade in process efficiency and environmental performance.

In carpet production, the drying process often consumes large amounts of energy due to the high water content of regular latex. High Solid SBR significantly reduces this burden by minimizing the water portion in the emulsion. Less water means faster drying, shorter production cycles, and reduced operational costs. Manufacturers can expect up to 25 percent energy savings during the curing process.

In addition to energy efficiency, HS-SBR provides stronger adhesion and mechanical strength in the carpet backing. The cured film forms a dense, uniform layer that resists cracking and powdering. Even under high filler loading, often above 200 phr of calcium carbonate, the latex maintains stable viscosity and smooth coating flow. This ensures uniform application and high-quality backing appearance.

HS-SBR also demonstrates good storage and mechanical stability. It can withstand pumping and high shear mixing without coagulation, which is essential for continuous production lines. Its low foaming tendency further improves handling and consistency in large-scale operations.

With increasing focus on sustainability and cost control, HS-SBR has become the preferred choice for both primary and secondary carpet backing applications. It supports greener manufacturing while delivering product durability.
