The grade also suitable for extrusion are indicated by the EG or AE end code and consequently they have to be ordered with such code when used in this application.

This technical note has been written on baseing our present best knowledge but the above mentioned data have not to be released as a specification for the material in object.

Properties reported in this Data Sheet are determined on annealed specimens obtained by injected test plaques and mostly represent an average of values gathered from a significative number of production lots.

Even if we guarantee the quality consistency of the LARIPUR products we could periodically issue up-dated version of this Technical Data Sheet and modify the respective sales specification as well .

PROCESS RECOMMENDATION

Predrying Material needs to be dried prior processing at 80°-90°C for 3 hours, preferably using a
