Benefits

  • Arnitel® TPC allows for light weight solutions (75% lighter compared to rubber)
  • Arnitel® TPC allows for cost effective solutions (up to 50% lower system costs than rubber)
  • Arnitel® TPC allows for sustainable solutions (compared to PA12, Arnitel® is a plasticizer free solution)
  • Arnitel® TPC allows for reliable solutions due to its peak temperatures resistance up to 180°C – 200°C and its good heat aging due to continuous use temperatures 120°C – 170°C
