Resin (IIR)
Calcined product, vinyl functionalized.
Aktifit VM as counter product to surface-treated calcined kaolinite offers improved processing and aging properties as well as better compression set.
- very low sieve residue
- very low chloride content
- long flow time with short vulcanization time
- high tensile modulus
- low compression set
- good hot air aging properties
- sealing tightness at high soldering temperatures
