LCP Product Chemical Resistance Application
Problem Phenomenon
Chemical environment applications.
Cause Analysis
LCP has excellent chemical resistance; but product defects (weld lines) are breakthrough points for chemical attack.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solution
①Keep weld lines away from medium contact areas; ②select chemical-resistant grades; ③perform medium immersion verification; ④structurally complete design.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP's chemical resistance advantage requires product integrity to cooperate; weld lines are weak points.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
