Heisssiegelbarer, coextrudierter Polymerfilm aus Flüssigkristall

摘要

A coextruded liquid crystal polymer ("LCP") film or sheet wherein a higher melting LCP layer is laminated to a lower melting LCP layer. These LCP components are coextruded from the same die. This film or sheet may then be laminated onto other materials at a temperature between the melting point of the lower-melting LCP and the higher-melting LCP, so that the latter LCP may maintain its shape, orientation, and mechanical characteristics while the lower-melting LCP component flows and bonds with the other material. When the higher-melting LCP layer is sandwiched between two lower-melting layers, the film or sheet may be laminated on two sides thereof.
