AEPDS chemical resistance
Problem Phenomenon
AEPDS chemical resistance, provided by acrylonitrile but different from ABS.
Cause Analysis
AEPDS acrylonitrile provides heat and chemical resistance; but EPDM differs from butadiene; specific media; stress cracking; verification need.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Media compatibility test; ②stress management; ③use assessment; ④long-term verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable each time and record parameter changes to facilitate locating effective measures
Key Takeaway
AEPDS chemical resistance needs specific verification; stress and media act together; assessment ensures application.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
