Polymer-modified bitumen is used in construction applications where the properties of conventional bitumen need to be adjusted for specific performance requirements.
SBR latex provides a water-based route for incorporating synthetic rubber polymer into selected bitumen systems.
SBR polymer can influence the flexibility, elasticity and cohesion of the modified binder.
Potential formulation objectives include:
The final performance depends on polymer characteristics, bitumen type, dosage and processing conditions.
High Solid SBR Latex contains a higher proportion of polymer solids than conventional latex grades.
For polymer-modified bitumen formulations, this can provide flexibility in controlling polymer concentration and water content.
The latex should be evaluated for compatibility with the selected bitumen and emulsifier system.
Potential applications include:
RUICO supplies High Solid SBR Latex for customers developing polymer-modified bitumen and asphalt systems.
