Agrifiber board

Agrifiber board

A composite panel product derived from recovered agricultural waste fiber from sources including, but not limited to, cereal straw, sugarcane bagasse, sunflower husk, walnut shells, coconut husks, and agricultural prunings. The raw fibers are processed and mixed with resins to produce panel products with characteristics similar to those derived from wood fiber.

Without fiber modification (e.g., mild chemical and steam pretreatment and fiber bundle refining) to improve buffering capacity and surface functionality, PMDI resin (up to 6% resin solids or higher, dry fiber weight basis) has been shown to be the preferred binder for most agrifiber boards. Therefore, the adhesive costs for these nonwood materials are often up to three times more expensive for a given volume than for comparable wood-based composites bonded with 6 to 12 percent UF resin solids, dry fiber weight basis.
