Aktifit VM in building profiles

Calcined product, vinyl functionalized.

Aktifit VM offers very low moisture content. Thereby the blistering potential will be reduced and there is a low need for moisture absorber for pressureless vulcanization. The product offers higher tensile strength, higher tensile modulus and lower compression set and higher loading of filler/plasticizer. With Aktifit a lower concentration of peroxide is possible.

 

  • low to very low moisture content
  • enables high loading of filler and plasticizer
  • excellent extrusion properties
  • high surface quality
  • high tensile modulus
  • low compression set
