Flexible sheet reinforced with poly(aromatic amide) non-woven fabric and use thereof |
| 摘要 |
A flexible sheet which comprises a non-woven fabric made predominantly from a poly(aromatic amide) component which is impregnated with a heat- and/or light-curable resin, wherein the non-woven fabric satisfies the following conditions: 5 g/m2<weight per unit area<35 g/m2, and 0.15 g/cm3</=density</=0.8 g/cm3, which has well balanced properties, such as excellent heat dimensional stability, heat resistance (soldering resistance), water resistance, solvent resistance, electrical insulating properties and mechanical properties and is useful for the preparation of a flexible printed circuit board, and use thereof for a flexible metal-clad laminate and a flexible printed circuit board.
