Material Drying

PEEK pellets rapidly regain moisture after drying
Problem Phenomenon
After drying, the material exceeds the moisture standard after 30 minutes of exposure to air
Cause Analysis
PEEK absorbs moisture quickly (saturated water absorption 0.5%); workshop humidity too high (southern region >70%RH); exposure between the drying hopper and the '2079851475616104452 machine
Solution
Use a drying hopper for continuous feeding (sealed system); store dried material in sealed containers or direct hot material supply; workshop environment dehumidification to control humidity <40%RH
Key Takeaway
PEEK's sensitivity to moisture requires moisture protection throughout the process
