LCP (Liquid Crystal Polymer)
Description

LCPs are a class of aromatic polymers that exhibit exceptional strength and rigidity. It is five times stronger than steel and ten times stronger than aluminum. It can replace some materials such as ceramics, metals, composites, and other plastics because its some properties perform very well in harsh environments, including heat resistance and tolerance, high electrical resistance, excellent chemical resistance, inherent flame retardancy, good weatherability, and biocompatibility for medical applications.

Features
  • Good Chemical Resistance:Resistant to hydrolysis, weak acids and bases, alcohols, chlorinated hydrocarbons, esters, and ketones…
  • High Dielectric Strength:Its dielectric strength is much higher than common plastics.
  • Excellent Resistance to creep, fatigue, high impacts, cuts and abrasion.
  • Good Cycle Repeatability:LCP’s high melt flow and low thermal expansion in the direction of molecular orientation allows thin-walled parts to be easily molded without the part warping.
  • Outstanding Dimensional Stability
Applications

ropes & cables, electronic support structures, sailcloth, reinforced hulls, fishing poles and lines, tennis strings, tennis rackets bicycle forks, golf clubs, hockey sticks, paragliders, skis, snowboards, automotive ignition system components, heater plug connectors, lamp sockets, transmission system components, pump components, coil forms and sunlight sensors and sensors for car safety belts…
