PETG transparency loss after toughening
Sorun Belirtisi
After PETG toughening modification, the transparency decreases severely, becoming translucent to opaque.
Neden Analizi
The refractive index of the toughening agent elastomer does not match PETG, and the toughening agent dispersed phase size is too large (>visible light wavelength) causing light scattering.
Çözüm
Select a toughening system with matching refractive index; optimize the dispersion process to make the toughening phase <100nm nano-toughening; control the toughening agent dosage.
Temel Çıkarım
PETG toughening with transparency requires refractive index matching and nano-scale dispersion.
