Q
PEEK pellets rapidly regain moisture after drying
A
PEEK's sensitivity to moisture requires moisture protection throughout the process
Material Drying moisture regainhygroscopicitydrying hoppersealed storageworkshop dehumidification
Q
Insufficient melt flowability, mold filling difficulty
A
PEEK's high melting point determines that extremely high processing temperature and pressure are required to ensure flowability

Q
Product bubbles/internal pores
A
Trace moisture at PEEK's extremely high processing temperature (>360°C) can produce a large number of bubbles
