Problem & Solution

Q

Defects caused by insufficient drying before cross-linked polyethylene cross-linked polyethylene processing (Variant: strengthened measures)

A

Insufficient drying is a common root cause of processing defects, and a complete drying system and moisture content detection system needs to be established. Targeted preventive measures need to be taken in different production scenarios.
