The product range includes powder styrene-butadiene rubber, granular styrene-butadiene rubber, asphalt modifiers, emulsified asphalt modifiers, and rubber product additives. These products demonstrate extremely high resistance to deformation at high temperatures, excellent low-temperature cracking ability, and superior water resistance. They maintain excellent adhesion and deformation adaptability to road surfaces, performing exceptionally well in elastic recovery.
Powder styrene-butadiene rubber is a high-molecular elastomer material formed by the polymerization of butadiene and styrene. It features small particle size, narrow distribution, and good water resistance. This modified rubber powder provides special efficiency, combining compatibility with road asphalt with quick bonding and flexible proportioning.
