Description
[Roseburg] Medex® A brand name for a moisture resistant, medium-density Fiberboard (MDF) that is made from cellulosic fibers bonded with a polyurea-isocyanate 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.
Synonyms and Related Terms
Applications
Medex® is commonly used as a structural material for pedestals, display decks, display panels and risers.
Personal Risks
Produces fine wood dust. Potential eye and respiratory irritant. Dust should be collected by suction cleaning equipment.
Medex SDS [1]
Collection Risks
| Collection Material | Risk |
|---|---|
| Pb, Zn, Cd metals | Corrosion |
| Calcium based objects (limestone, shell, coral, pearl) | Efflorescence |
| Some color photographs | Fading |
| Pb glazed ceramics | Efflorescence |
The risks of organic acids to collections can be mitigated by using barrier materials.
