As far as the dies are concerned, the same flow and heating guidelines apply as for adapters.

Desmopan® and Texin™ can be processed with side-fed dies (Fig. 2), spider-type dies (Fig. 3), flat film dies (Fig. 4) and flat-film coextrusion dies (Fig. 5).

The tools must allow a uniform flow front and be equipped with an easily centered die with a parallel guide (die land).
