PETG flame retardant formulation poor processability
Fenómeno do problema
After adding flame retardant, the melt flowability decreases significantly, making injection filling difficult.
Análise das causas
The flame retardant filling amount is large affecting flowability, and the flame retardant has poor compatibility with PETG.
Solução
Select a flame retardant system with little impact on flowability (phosphorus-based); add lubricant; appropriately increase the processing temperature.
Conclusão principal
PETG flame retardant modification needs to balance flame retardancy and processability.
