Q

PCABS processing temperature looser than pure PC

A

The looser processing of PCABS than pure PC is an efficiency advantage; but drying is still necessary; management ensures quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying PCABS；loose processing；pure PC；drying；flowability；warpage

Q

PCABS drying temperature and time

A

Supplier differences in PCABS drying must be confirmed; dehumidifying dryers are standard equipment; moisture content verification is the final criterion.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Drying PCABS；drying；80-110℃；3-4 hours；dehumidification；dew point

Q

PCABS hydrolysis strength loss 50%

A

PCABS hydrolysis is the culprit of 50% strength loss; the 0.02% moisture content red line must be quantitatively verified; visual judgment of drying is a fatal error.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
