Abstract
A multilayer foam panel member including: (a) at least one top sheet substrate; (b) at least one bottom sheet substrate; and (c) a middle substrate of foam material disposed inbetween, and integral with, the top and bottom sheet substrates; wherein the foam material is produced by dispensing a reactive foam-forming fluid mixture onto a moving or stationary bottom sheet substrate of a foam manufacturing line; and wherein the foam manufacturing line includes a flexible film fluid dispensing device for dispensing the reactive foam-forming fluid mixture onto the moving or stationary bottom sheet substrate to form a multilayer foam panel member; wherein the middle substrate of foam material of the panel member has improved thermal and mechanical properties; and a process for manufacturing the above multilayer foam panel member.
