摘要:
A composite board with a multilayer laminated facer is presented having a nonwoven, a first polymer layer, and a second polymer layer. The laminate may be printed on the nonwoven, on the upper surface of the first polymer layer or inverted printed on the backside of an applied film. A number of configurations for the polymer layers are disclosed. The laminate may include exposed fibers on the lower surface or the nonwoven may be saturated. A removable peel-ply may be included. By controlling the placement and thickness of the polymer layers it is possible to tailor additive in the polymers such as colorants, opacifiers, UV stabilizers, and fire retardants to improve quality and reduce costs. In an alternate embodiment of the present invention, a first polymer layer is applied to the topside of the nonwoven and the second polymer is laminated to the first polymer layer as a preformed film. The laminated facer is thermally or adhesively bonded to the composite board.
