Product Position:
SBR styrene-butadiene rubber latex is a stable aqueous emulsion produced by low-temperature emulsion polymerization of butadiene and styrene, specifically developed for modified emulsified asphalt and modified asphalt. Widely used in road engineering for spray-grade and mix-grade modified emulsified asphalt, it significantly improves high and low temperature performance, elastic recovery and aging resistance of asphalt.
