[Medite Corp.] A brand name for a medium-density fiberboard that is made from cellulosic fibers bonded with a polyurea-isocyantate resin, then compressed into a hardboard. Medex is waterproof, smooth, heavier than plywood and slightly acidic (pH=5.5). Medex uses a formaldehyde-free adhesive but the wood fibers may still emit small amounts of organic acids such as acetic acid.
Hazards and Safety
Any wood product may release organic acids with time.
