PETG regrind performance degradation
Sorun Belirtisi
After adding PETG crushed regrind, the impact strength and transparency of new products decrease significantly.
Neden Analizi
The regrind undergoes multiple thermal histories and molecular chains degrade, crushing produces dust, and increased moisture absorption increases hydrolytic degradation.
Çözüm
Control the regrind ratio ≤30%; use after full drying; add antioxidant and stabilizer during pelletizing.
Temel Çıkarım
PETG reuse requires controlling the ratio and performing stabilization treatment.
