LCP Vectra E130i is a 30% glass-fiber reinforced liquid crystal polymer specifically formulated for ultra-fine-pitch electronic connectors. Its near-zero flow-direction shrinkage (0.05-0.15%) enables molding of connectors with 0.3mm pitch at wall thicknesses as low as 0.15mm — geometries that are impossible with any other thermoplastic. The glass fiber reduces the extreme anisotropy of unfilled LCP while maintaining the exceptional flowability that defines LCP processing.

Frequently Asked Questions
What connector pitches require LCP vs PPS?
LCP E130i is required for connectors with pitch ≤0.5mm and wall thickness ≤0.25mm. PPS GF40 can handle pitch ≥1.0mm with walls ≥0.4mm. The economic crossover is at approximately 0.5mm pitch — below this, LCP is required regardless of cost; above it, PPS offers comparable performance at lower material cost.
