Aktifit PF 111 in sealants and membranes

Calcined product, treated with alkyl silane.

Aktifit PF 111 offers higher rheological activity (higher viscosity at low shear rates, yield point, greater shear thinning).

 

  • selectable rheology (free-flowing to non-sagging)
  • good mechanical properties (high strength)
  • good chemical resistance
  • also suitable for food contact and drinking water applications (as per BfR and FDA regulations)
