PETG regrind performance degradation
문제 현상
After adding PETG crushed regrind, the impact strength and transparency of new products decrease significantly.
원인 분석
The regrind undergoes multiple thermal histories and molecular chains degrade, crushing produces dust, and increased moisture absorption increases hydrolytic degradation.
해결 방법
Control the regrind ratio ≤30%; use after full drying; add antioxidant and stabilizer during pelletizing.
핵심 요약
PETG reuse requires controlling the ratio and performing stabilization treatment.
