- Application Data
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.
- Hot Charged Air Ducts Application Data
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.
