PETG transparency loss after toughening
ظاهرة المشكلة
After PETG toughening modification, the transparency decreases severely, becoming translucent to opaque.
تحليل الأسباب
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.
الحل
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.
الخلاصة الأساسية
PETG toughening with transparency requires refractive index matching and nano-scale dispersion.
