Processing Main Considerations:
A: It is recommended to dry at 80°C for 2–4 hours.
B: It is recommended to clean the screw or die head with polypropylene or polyethylene before and after processing this material.
C: Scrap material can be reused. It needs to be dried before use. The addition amount generally should not exceed 15%, and the performance is basically unaffected.
