Quality degradation of PMMA regrind
Problem Phenomenon
The transparency and impact strength of recycled PMMA material decrease.
Cause Analysis
Recycled material has undergone multiple heat histories and molecular chain scission, making it difficult to restore initial performance.
Solution
Control recycled material addition ratio ≤20%; add reinforcing stabilizer.
Key Takeaway
PMMA recycling reducing quality is the price.
