Unsuitable screw compression ratio for PCTG
Problem Phenomenon
General-purpose screw compression ratio is not suitable for PCTG, causing plasticizing problems.
Cause Analysis
Compression ratio too large or too small, mismatched with PCTG rheological characteristics.
Solution
Use a PCTG dedicated screw with compression ratio 2.0-2.5:1.
Key Takeaway
PCTG needs a screw with a suitable compression ratio.
