Claims14
A molding process comprising
- providing an uncured blank including fibers and uncured binder,
- molding the uncured blank to establish a shaped product having a molded shape that does not change after removal from a mold cavity formed in a mold, the shaped product including the fibers, a first portion of cured binder, and a remainder of the uncured binder,
- wherein the uncured binder comprises:
- at least 50% by dry weight of a carbohydrate reactant selected from one or more reducing sugars, one or more carbohydrate reactants that yield one or more reducing sugars in situ under thermal curing conditions and combinations thereof;
- and
- at least 10% by dry weight of a nitrogen-containing reactant selected from ammonia, ammonium salts, inorganic amines, inorganic amine salts, organic amines comprising at least one primary amine group, salts of organic amines comprising at least one primary amine group, and combinations thereof.
