Royflexa Rubber
1 / 5
The company is a key domestic manufacturer specializing in the production of powder styrene-butadiene rubber, granular styrene-butadiene rubber, asphalt modifiers, emulsified asphalt modifiers, and rubber product additives.
The products have extremely high resistance to deformation at high temperatures, low-temperature cracking ability, water resistance capability, and maintain excellent adhesion and deformation adaptability to the road surface. Moreover, they perform exceptionally well in terms of elastic recovery performance.
Through close cooperation with research institutions, the developed leading products include: powder styrene-butadiene rubber (PSBR), SBR anionic emulsified asphalt modifier and SBR cationic emulsified asphalt modifier, high-performance high-content SBR granular styrene-butadiene rubber, asphalt tackifier, etc. These products have been widely applied in high-grade highways, bridge decks, airport inspection vehicles, and other fields.
Styrene-butadiene rubber powder and granules are widely used as road asphalt modifiers, asphalt thickeners, high-viscosity asphalt, water conservancy asphalt, and rubber products. They not only have excellent low-temperature resistance, but also possess excellent high and low-temperature properties and elastic recovery ability.
Powder styrene-butadiene rubber is a high-molecular elastomer material formed by polymerization of two monomers, butadiene and styrene. Depending on the different uses, other monomers can be appropriately grafted. This product has the characteristics of small particle size, narrow distribution, good water resistance, and convenient use.
