SBS polymer-modified bitumens (PMB) provide asphalt pavements with enhanced mechanical and aging characteristics. When used appropriately, PMBs enhance the pavements’ economic and environmental value. Kraton offers a broad range of SBS polymers designed to work in even the most complex bitumen sources, providing the right balance of material properties.

These two categories encompass polymer loading levels of 2-6 wt. % of SBS in bitumen. As the modification level increases, the bitumen becomes increasingly better at resisting high-temperature deformation and intermediate temperature cracking. The effect is dependent on polymer content, type, and the formulation process.
