Medex

Description

[Medite Corp.] A brand name for a moisture resistant, medium-density fiberboard (MDF) 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. Medex is sustainable using a 100% post-industrial recycled wood fiber.

Handling and Workability

• Readily accepts and holds hardware including staples, screws, other wood fastening hardware. Ideal for pressure fitting mounts.

Hazards and Safety

Produces fine wood dust. Potential eye and respiratory irritant. Dust should be collected by suction cleaning equipment. Any wood product may release organic acids with time.
