Delamination or poor interface in K-RESIN and PS blended products
Problembeschreibung
Delamination or poor interface appears in K-RESIN and PS blended products
Ursachenanalyse
Limited compatibility between K-RESIN and PS, weak interfacial bonding
Improper compounding temperature (deviating from 200-240°C)
Improper K-RESIN/PS ratio
Insufficient compounding time, uneven dispersion
Shrinkage rate difference between the two materials causes interfacial stress
Lösung
Optimize K-RESIN/PS ratio
Strictly control compounding temperature according to the 200-240°C range
Extend compounding time to ensure dispersion
Add compatibilizer to improve the interface
Consider shrinkage rate difference in design
Wichtigste Erkenntnis
K-RESIN/PS blending needs to optimize ratio and compatibility
