REEL MADE OF MOLDED COMPONENTS
20180009628 · 2018-01-11 · ·

A composition for making a molded article such as a reel flange, and a method making the same, are provided. The composition may consist essentially of about 75-95 wt % dry waste wood and about 10-25 wt % binder such as melamine-urea-formaldehyde (MUF) or PMUF resin. The waste wood may be recycled wood fiber from pine or other hardwoods, sawdust and wood chips. The method comprises mixing dry waste wood with MUF or PMUF resin binder to make a wood/resin mixture, and compressing the wood/resin mixture in a mold cavity at a pressure and temperature.
