The polyamide products listed in Table 1 (grade: Vestamid, manufacturer: Degussa-Hüls) are extrusion compounds based on semi-crystalline polyamide 12. Of all the polyamides, PA 12 has the lowest density and water absorption, as well as the lowest melting point. Its low water absorption ensures good ...

All tubing structures are based in principle on the same outer layer structure of PA12/adhesion promoter/EVOH. A plasticised, impact-modified PA12 (grade: Vestamid, manufacturer: Degussa AG, Marl/Germany) is used as the outer layer.
