High LCP Cost and Material Substitution Evaluation
Problem Phenomenon
【Problem Phenomenon】The price of LCP raw material is about 16 USD/lb, product cost pressure is high, and it is necessary to evaluate whether substitution or cost reduction is possible
Cause Analysis
LCP synthesis process is complex and capacity is concentrated, so its price is significantly higher than conventional engineering plastics; Fictiv literature quotes about 16.25 USD/lb; literature such as 52by shows that PA9T/PA6T/PPS/high-performance PBT can partially substitute
Solution
Evaluate substitution according to heat resistance, thin-wall flow and dimensional stability requirements: reflow-soldered parts can be verified with PA9T/PPS; non-soldered parts consider high-performance PBT; for cost reduction, prioritize optimizing wall thickness and regrind ratio rather than easily changing material
Key Takeaway
LCP's high cost should be absorbed by thin-wall design and regrind management; substitute materials must pass soldering verification; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
