Liquid Crystal Polymer: Techno Brief

This technology brief features key facts about Liquid Crystal Polymer (LCP). It includes LCP strengths, limitations, processing guidelines, properties and applications.

Liquid Crystal Polymer

  • Chemically aromatic copolyesters
  • Self-reinforcing materials
  • High temperature resistance
  • Heat distortion temperature (170–350°C)
  • Excellent mechanical properties
  • Good solvent resistance
  • Good chemical resistance (thin walled applications)
  • Low water absorption
  • Recyclable
  • Low coefficient of thermal expansion
  • Good electrical insulation properties
  • Fire resistant at higher temperatures
  • Low flammability with a limiting oxygen index (range of 35 to 40)
  • High specific gravity of about 1.4.
Liquid Crystal Polymer shows little dimensional change when exposed to high temperatures. Liquid Crystal Polymer applications include automotive, healthcare/medical, electrical/electronics (sockets, connectors, switches, sensors, etc.) amongst various others.
