<p>A method for reducing the anisotropy of an LCP film and producing a film having modified or more balanced properties. The film is calendered by one or more nip rolls in the transverse direction at a temperature sufficient to soften the polymer film so that it will flow under pressure from the rolls, but not so high as to melt the polymer. The nip roll gap and pressure may be set to produce various drawdown ratios. Generally, the greater is the drawdown ratio, the greater is the modification in the film's properties.</p> |
