Recommended pre-drying Conditions・ We strongly recommend to dry before processing.

・ To achieve the effective drying, it is better to use hopper dryer. ・The hopper dryer should have the capacity of more than 6 hours consumption of the resin.・Typical drying condition :

・ When using the vent-type extrusion machine, the pre-drying does not be needed
