Our Laser Compatible Medite Premier MDF sheets are highly versatile, suitable for enclosures and many other applications. Please note: As wood is a natural product, there is often a crook or bow to the sheet. The natural twist might be in excess of 10mm (see below - Tolerances and Caution).

Medite Premier MDF is produced using superior wood refining technology and specially designed resins. Benefits are consistency of quality and thickness, as well as reduced tool wear. Medite Premier MDF retains the light tan colour of the wood fibre from which it is manufactured.

This product conforms to E1 (low) formaldehyde levels as well as also complying with the lower levels required by CARB phase 2 (CARB Phase 2 compliant <0.11ppm).

This product is often described as 'Laser Grade' MDF but there is no official classification for this. We believe that E1 conforming MDF is the safest and best MDF for using in a laser cutter.
