<p><P>PROBLEM TO BE SOLVED: To provide a high strength (high hardness) insulating material capable of sustaining its low dielectric constant and low dielectric loss tangent even being preserved under high-humidity environment, and molded products such as a connector, a heat shrinkable tube and an electrical insulated wire using the material for insulating coating. <P>SOLUTION: These products are fabricated by extrusion-molding of a composition of which main component is a polyamide made by polycondensation of an aliphatic dicarboxylic acid having an average carbon number of 13 or more and a diamine containing an alicyclic diamine by 50 mol% or more. The dicarboxylic acid preferably contain a dimer acid by at least 50 mol%, and the alicyclic diamine is preferably a 1,3-diaminocyclohexane derivative. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
