Molded gaskets, o-rings and radial shaft seals

Advantages

  • very low sieve residue
  • good mixing and dispersion properties
  • long flow time with short vulcanization time
  • easy deflashing
  • low compression set
  • good resistance against fuel, oil, water, acid
  • avoidance of mold fouling caused by filler
