NB-45-4 is a medium density fiberboard (MDF) panel produced by Newbrand. The panel is made of fine wood fibers compressed under high pressure and heat, combining the strength of plywood with the aesthetic appeal of a real wood panel. The panel is rotary and tension-die cut, making it perfect for CNC machining, laser cutting, carving, and routing, among many other applications. The finish of the board is smooth, while the edges are beveled to provide a clean, attractive appearance. The board is also formaldehyde free and environmentally friendly, making it a great choice for many projects.
