PETG flame retardant formulation poor processability
ظاهرة المشكلة
After adding flame retardant, the melt flowability decreases significantly, making injection filling difficult.
تحليل الأسباب
The flame retardant filling amount is large affecting flowability, and the flame retardant has poor compatibility with PETG.
الحل
Select a flame retardant system with little impact on flowability (phosphorus-based); add lubricant; appropriately increase the processing temperature.
الخلاصة الأساسية
PETG flame retardant modification needs to balance flame retardancy and processability.
