A product and method comprising a cellulose based release layer. The cellulose release layer comprising cellulose particles having at least one dimension in the nanoscale range. The cellulose release layer being between a mold surface and moldable mixture surface during a molding process. The method comprising releasing a moldable mixture from a mold where the moldable mixture may include a pre-adhesive. A molded product comprising a release layer on its surface after molding.

A process or method for manufacturing a fire-retardant treated wood composite board or panel, such as oriented-strand board, with a low melting point fire retardant (FR) material, such as boric acid, while the press is operating at typical press temperatures above the FR material melting point. An intervening overlay is applied to the top surface of the mat on the forming line, after the use or application of any FR material within or on the mat, prior to entry into the press. The intervening overlay covers the top surface so as to prevent the melting fire retardant material from contacting the press platen(s). After pressing, the intervening overlay may be removed from the top surface by sanding, buffing, or other methods. The intervening overlay also may be sized so as to extend over one or more edges of the underlying panel, for ease of removal post-process.

A product and method comprising a cellulose based release layer. The cellulose release layer comprising cellulose particles having at least one dimension in the nanoscale range. The cellulose release layer being between a mold surface and moldable mixture surface during a molding process. The method comprising releasing a moldable mixture from a mold where the moldable mixture may include a pre-adhesive. A molded product comprising a release layer on its surface after molding.

A method and a plant for the production of material boards from at least one material which is spread to form a press mat and mixed with at least one binder curable by heat and/or pressure. The press mat is compressed in a double belt press with steel belts warmer than the press mat, and is heated by heat conduction. At least one cover layer resting against a steel belt is heated to a temperature above the curing temperature of the binder and cured at least partially. The uncured parts of the press mat are heated and cured in a downstream injection press by introducing tempered fluids to a temperature above the curing temperature of the binder. Fluids are introduced into or through the press mat through one or both cover layers. Also provided are a material board produced by a method and/or in such a plant.
