Problem & Solution
Practical answers to common plastic material challenges
Unstable EPS pre-foaming ratio
Incorrect catalyst/foaming agent/foam stabilizer ratio
Mismatch between foaming speed and gelation speed
Improper open-cell ratio
Insufficient closed-cell ratio (poor thermal insulation performance)
Black core/yellow core (carbonization from excessive heat release)
Foam bottom scorching/core burning (internal overheating)
Foam Collapse/Foam Shrinkage
