Bottleneck of PCTG Replacing Polycarbonate
Problem Phenomenon
When PCTG replaces PC in certain applications, insufficient heat resistance is found.
Cause Analysis
PCTG HDT 65-75°C < PC HDT 125-135°C, the heat resistance grades are different.
Solution
Correctly evaluate the heat resistance requirements; be sure to verify the feasibility of the substitute material.
Key Takeaway
PCTG cannot simply replace PC and requires comprehensive evaluation.
