Quality Decline After Using Recycled PCTG Material
Problem Phenomenon
After adding recycled PCTG material, the transparency and impact strength of the products decrease.
Cause Analysis
The recycled material has experienced thermal history, causing molecular chain degradation, color deepening, and impurity introduction.
Solution
Control the recycled material ratio ≤25%; fully clean and dry the recycled material; add stabilizers when necessary.
Key Takeaway
PCTG recycling requires control of the ratio and quality.
