Aktifit PF 111 in sealing tapes

Calcined product, treated with alkyl silane.

Aktifit PF 111 offers lower water absorption of unvulcanized mixtures as well as higher brightness and color neutrality.

 

  • good processing properties
  • good calendering properties
  • balanced ratio of tensile stress/modulus/tear resistance
