Poor compatibility and delamination of PET modified material
ظاهرة المشكلة
Obvious delamination and poor mechanical properties when PET is blended with PE, PP and other polymers for modification.
تحليل الأسباب
PET and non-polar polymers are thermodynamically incompatible with large interfacial tension, no compatibilizer used or insufficient dosage, improper mixing parameters.
الحل
Use suitable compatibilizers (SEBS-g-MAH, etc.); optimize mixing process (twin-screw, appropriate shear and temperature); control compatibilizer 3-8%.
الخلاصة الأساسية
The core of PET blend modification lies in improving interfacial compatibility.
