LCPs feature properties not available in other resins.

Unlike other semicrystalline resins, liquid-crystal polymers (LCPs) are made of rigid, well-ordered, rod-like molecules. This structure enables LCPs to display properties unmatched by other resins. Vectra and Vectran LCPs feature consistent flow during the molding of thin-wall parts, dimensional stability of parts at high temperatures, high impact strength, chemical and flame resistance, and a low coefficient of expansion. Vectra LCP provides low moisture absorption to maintain its dielectric properties, and is suitable for high-frequency applications and electronic films. High-temperature resistance makes Vectra an ideal material for use in the manufacture and assembly of miniature devices, while the barrier properties exhibited by Vectran LCP are useful in packaging applications. Both LCPs, manufactured by Ticona (Summit, NJ; 800/833-4882), are part of a line of LCP grades that includes packaging film and high-temperature and FDA grades.
