LIQUID CRYSTAL POLYMER FILM

PROBLEM TO BE SOLVED: To provide a film having substantially uniform thermal expansion coefficient in all planar directions in spite of a local unevenness of thermal expansion coefficients of flat layers according to a direction. SOLUTION: A film structure comprises two relatively thin outer layer o...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a film having substantially uniform thermal expansion coefficient in all planar directions in spite of a local unevenness of thermal expansion coefficients of flat layers according to a direction. SOLUTION: A film structure comprises two relatively thin outer layer oriented by a double wall or triple wall tube extrusion die so as to be controllable in a certain direction and one or more relatively thick inner layer oriented so as to be controllable in one or more different directions.
