ABSTRACT:
The improved thermotropic LCP composition comprises 10-13 wt. % of a thermotropic liquid crystal polymer resin and 90-87 wt. % of zircon and is useful as an electrical insulator. The composition is a good electrical insulator, permits good heat conduction and experiences small thermal expansion, thus insuring high reliability. The composition may be injection molded to form an electrically insulated housing of a stator for electric machines or appliances that includes a coil and terminals thereof.
