LIQUID CRYSTAL POLYMER (LCP)

Advantages

  • Excellent moldability in thin sections
  • Outstanding chemical resistance
  • Heat resistance

Limitations

  • Cost
  • Knit line strength

Overview

Liquid crystal polymer (LCP) exhibits a highly ordered structure in both the melt and solid states. LCP can replace such materials as ceramics, metals, composites and other plastics because of its outstanding strength at extreme temperatures and resistance to virtually all chemicals, weathering, radiation and burning.

Although based on polyester chemistry, LCP’s have heat deflection temperatures as high as 610 degrees F (321 degrees C) at 264 psi when reinforced with glass fiber.

The resin’s high melt flow and fast setup permits it to be molded into large, heavywalled parts as well as thinwalled components. Its thermal stability permits efficient use of regrind.

Applications of LCP’s include those that require resistance to high temperatures and chemicals.
