AEPDS impact strength
Problem Phenomenon
AEPDS impact strength management, rubber content and dispersion influence.
Cause Analysis
AEPDS impact strength depends on EPDM rubber content and dispersion; rubber particle size; interfacial bonding; processing shear influence; batch consistency.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Rubber content grade selection; ②dispersion quality; ③shear control; ④impact test; ⑤batch management.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
AEPDS impact strength is the result of rubber phase management; dispersion and shear are process keys; testing ensures consistency.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
