Fluoropolymer laminates and a process for manufacture thereof

摘要

The present invention provides fluoropolymer laminates having isotropic properties. For example, an embodiment in which multiple fluoropolymer sheets having a liquid crystalline polymer oriented in the fibrous state in the melt processible fluoropolymer are laminated, despite having the fibrous LCP oriented in one direction in each single extruded sheet, makes it possible to laminate in such a way as to compensate for their orientation directions, the laminate thereby becoming isotropic as regards physical properties. The laminates also have low linear coefficient of expansion and low thermal shrinkage as well as elevated tensile modulus and low dielectric constant.
