9 If the intended use of the product is for the manufacture of a pharmaceutical, medical device or of intermediate products for medical devices or for otherspecifically regulated applications which may lead to a regulatory obligation of Covestro, Covestro must be contacted in advance to provide its agreement to sell such product for such , any determination as to whether a product is appropriate for use in a pharmaceutical, medical device or intermediate products for medical devices or for the use in other specificallyregulated applications, must be made solely by the purchaser of the product without relying upon any representations by Covestro, irrespective of the existence of any regulatory obligation for theregistration, approval or notification. 1) Please see the "Guidance on Use of Covestro Products in a Medical Application" Processing and Drying ConditionsBarrel temperatures are valid for a standard 3-zone barrel.

10 Temperature set-up for different barrel types may change according to configuration. Values for hold pressure as percentage ofinjection pressure may vary depending on, amongst others, part geometry, injection Molding machine and injection mold. Drying conditions are for dry air dryers only. Drying times and dryingtemperatures may differ depending on valid dryer type.
