PPSU mold temperature requirements are high
Problem Phenomenon
PPSU needs mold temperature of 140-180°C to obtain optimal performance.
Cause Analysis
PPSU glass transition temperature is about 220°C; mold temperature needs to be high enough to reduce internal stress and improve performance.
Solution
Use oil temperature unit or electric heating mold to reach and maintain 140-180°C.
Key Takeaway
PPSU's extremely high mold temperature requirement is its processing feature.
