PETG flame retardant formulation poor processability
문제 현상
After adding flame retardant, the melt flowability decreases significantly, making injection filling difficult.
원인 분석
The flame retardant filling amount is large affecting flowability, and the flame retardant has poor compatibility with PETG.
해결 방법
Select a flame retardant system with little impact on flowability (phosphorus-based); add lubricant; appropriately increase the processing temperature.
핵심 요약
PETG flame retardant modification needs to balance flame retardancy and processability.
