Climate changes, increased traffic volumes, increasing wheel loads. All kinds of factors nowadays imposing limitations to the durability of asphalt pavements. The Sealoflex® SFB5 range of polymer modified binders has especially been designed to cope with these extreme loading cases. Sealoflex® SFB5 binders provide quality and durability without any compromise unrivalled by any kind of other asphalt binder.  

Properties Sealoflex® SFB5 is a SBS-polymer modified binder with relatively high polymer content. With the specially developed Sealoflex® processing technique the polymer is cross-linked and stabilized. Sealoflex® SFB5 binders have premium properties with respect to:

  • Temperature susceptibility
  • Elasticity and resistance to deformation
  • Ductility and resistance to fatigue
  • Ageing
  • Adhesion promotion  

Accordingly asphalt mixtures with Sealoflex® SFB5 are rut resistant, crack resistant and almost impossible to fatigue even in extreme load cases which is confirmed by results in laboratories and in practice.
