Polymer modification is commonly considered when asphalt binder systems require a different balance of flexibility, elasticity and resistance to deformation.
SBR latex provides a water-based polymer option for selected asphalt and bitumen formulations. The synthetic rubber polymer can be incorporated into suitable systems to modify the properties of the binder after formulation and curing.
SBR latex may contribute to:
The actual result depends on the SBR grade, polymer dosage, bitumen properties, formulation design and processing conditions.
High Solid SBR Latex contains a higher polymer solids concentration compared with conventional latex grades. This can help formulators introduce the required polymer dosage while managing the amount of water introduced into the system.
Typical parameters considered during grade selection include solids content, Tg, viscosity, particle characteristics, pH and compatibility with the bitumen system.
High Solid SBR Latex can be evaluated for polymer-modified asphalt, bitumen emulsions, pavement materials and selected waterproofing systems.
RUICO supplies SBR latex for customers developing polymer-modified construction materials.
