Corrosiveness of LCP degradation products
Problem Phenomenon
LCP degradation produces corrosive gases that affect the mold and screw.
Cause Analysis
The ester groups in LCP will hydrolyze or pyrolyze under excessive temperature to produce acid.
Solution
Use corrosion-resistant steel to manufacture molds and screws.
Key Takeaway
LCP corrosiveness is an additional risk of high-temperature processing.
