Quality Decline After Using Recycled PCTG Material
Fenómeno del problema
After adding recycled PCTG material, the transparency and impact strength of the products decrease.
Análisis de la causa
The recycled material has experienced thermal history, causing molecular chain degradation, color deepening, and impurity introduction.
Solución
Control the recycled material ratio ≤25%; fully clean and dry the recycled material; add stabilizers when necessary.
Conclusión clave
PCTG recycling requires control of the ratio and quality.
