Fluidity decline of PET modified material
Sorun Belirtisi
After adding fillers (glass fiber, mineral powder) or flame retardants to PET, MFI decreases significantly and '2079851475616104452 is difficult.
Neden Analizi
Rigid fillers increase melt viscosity (particle-particle and particle-molecular chain friction); fillers are not surface-treated.
Çözüm
Use silane coupling agents to treat fillers; control filler dosage and particle size distribution; add lubricants or flow modifiers.
Temel Çıkarım
The fluidity loss of PET filled modification needs to be compensated through filler surface treatment and process adjustment.
