Applications

Bed Springs

Industry
Consumer goods
  • <ul> <li>Arnitel® TPC allows for more design freedom, since due to high flow injection moldable viscosity grades, complex designs can be moulded easily</li> <li>Arnitel® TPC allow for reliable solutions due to high flexibility in various temperature regimes, excellent colourability and colour stability</li> </ul>

Railway Pads

Industry
Transportation
  • <ul> <li>Arnitel® TPC allows for cost effective solutions since it yields thermoplastic processing advantages over rubber, resulting in faster cycle times in compraison with other TPE's</li> <li>Arnitel® TPC allows for reliable solutions due to its high abrasion resistance, excellent load bearing capacity, great fatigue, and environmental resistance and due to a very consistent performance over temperature ranges from -55°C (-67°F) to +150°C (+300°F) and longest lifetime to failure as compared to any other rubber or class of TPE's used in this application</li> </ul>

Suit Case Handles
