Hot Charged Air Ducts Application Data

Details

Akulon® PA6 is used for temperature up to 150-180˚C.

Benefits

  • Stanyl® PA46, Stanyl® Diablo PA46, Akulon® Diablo PA and Arnitel® HT TPC allow for light weight solutions as compared to metal or rubber or alternative plastics (Stanyl® is 10% lighter than PPS)
  • Stanyl® PA46, Stanyl® Diablo PA46, Akulon® Diablo PA and Arnitel® HT TPC allow for cost effective solutions (Stanyl lowers system cost up to 20% versus metal)
  • Stanyl® PA46, Stanyl® Diablo PA46, Akulon® Diablo PA and Arnitel® HT TPC allow for reliable solutions (Stanyl® Diablo is long term resistant up to 230 ˚C, Akulon® Diablo ca be used around 200 ˚C) and Arnitel® HT is ideal as single part solution for flexible hot charge ducts.
Clean Air Inlet Ducts Application Data

Details

Blow molding grades and injection molding grades are available. For even higher temperatures Diablo grades are available.

Benefits

  • Arnitel® TPC allows for light weight solutions (50% lighter than rubber)
  • Arnitel® TPC allows for reliable solutions due to its perfect combination of high (aging) temperature resistance and good flexibility and chemical resistance
  • Akulon® PA6 allows for light weight solutions (50% lighter than metal) and for more rigid duct solutions.
