Poor EVOH Antistatic Effect
Problem Phenomenon
EVOH product surface resistance >10¹²Ω, severe static electricity
Cause Analysis
Antistatic agent addition insufficient <0.1wt%; antistatic agent migration rate slow, not reaching the surface
Solution
1) Increase antistatic agent to 0.3-0.5wt%; 2) Select antistatic agent with fast migration rate; 3) Surface coat antistatic liquid for immediate effect
Key Takeaway
Poor antistatic effect is caused by insufficient addition; increasing antistatic agent is key
