Note

Take care to ensure that XYRON™ is not predried for longer than 8 hours. Excessive predrying may result in degradation of physical properties and color changes.
Properly molded XYRON™ (sprues, runners, molded articles, etc.) may be reground, dried, and remolded without adverse effects. It is essential that material to be reground be free from oil, grease, dirt, and foreign substances, and shows no signs of degradation. Regrind levels up to 20% can be used successfully, but it is not advisable to use reground material for applications where surface appearances are critical.
High viscosity GPPS and Asaclean™ (available from Asahi Kasei Corporation and distributors) are recommended purging materials for all XYRON™ grades. Purging should be performed at temperature ranges appropriate for each grade.

In order to prevent polymer degradation when molding operation is stopped or interrupted, the following measures are recommended.

Within 30 minutes	Maintain cylinder temperature. Purge barrel using same material prior to the re-start of molding operation.
30 minutes to 12 hours	Decrease cylinder temperature to 200・20°C. Purge barrel using high viscosity GPPS. Upon commencement of molding operation, Purge barrel using material for molding after increasing cylinder temperature to the required level.
12 hours or more	Purge barrel with high viscosity GPPS, and shut down machine.

Generally, mold release agents are not required for molding XYRON™ resins. In cases where mold release agents are needed due to the complex shape of the mold, minimal use is recommended. Silicone-based mold release agents such as Pelicoat B™ (manufactured and sold by Chyukyo Kasei Kogyo Ltd., Japan) are recommended, as the chemical ingredients do not react with XYRON™.
