LCP materials
LCP (liquid crystal polymer) is considered for precision and miniaturized parts. Flow orientation can affect properties in different directions. Account for gate location, weld lines, wall thickness and specimen orientation, then test the intended connector or thin-wall part.
LCP handling and processing guide
This family-level guide is for preliminary screening, not a production recipe. Use the latest manufacturer instructions for the exact grade and equipment for drying, processing and safety settings; validate the process and part before production.
Storage
Store sealed, dry and clean with lot traceability; cleanliness matters for precision components.
Drying
Check grade processing instructions for drying and moisture targets. Keep conveying sealed after drying to limit reabsorption.
Equipment setup
Verify machine and mold temperature capability, venting and precision runners. Trial filling within supplier limits and examine thin walls, weld lines and flow-direction effects on strength.
Typical applications
Candidate uses include thin-wall connectors, electronic sockets and precision components. Validate actual thickness, soldering exposure and applicable approvals.
How to screen and compare grades
Start with the part’s operating temperature and exposure time, load, contact media, dimensional requirements and intended process. Compare specific manufacturers and grades: results with different test methods, specimen conditions, units or reinforcement are not automatically equivalent. A missing field means the information is unknown, not zero.
From data sheets to part validation
Use the database to build a shortlist, then request original data sheets, processing guidance and applicable certification from each manufacturer. Mold representative parts using the intended process and check dimensions, strength and function under the relevant combination of temperature, media and load; retain processing and lot records. Family-level guidance is not a guarantee for a particular grade.
