MDF V313 – humidity resistant – through-coloured black
FIBRALUX MR BLACK / Umidax Noir
V313 through-coloured-black Type MDF LA according to DIN 622-5 Datenblatt zum Download
approx. 720 kg/m3 bulk density
Area of application
Damp-resistant medium-density fibreboards , dyed black through to the core, for use in humid environments, equally suited for construction purposes with direct or short-term strain.
MDF with high density with a hard, finely sanded surface and a strong, screw-mountable core, glued with MUF glue. The boards are subject to minimum expansion and swelling with high humidity. MDF Umidax® Noir can be finished with paper, melamine, veneer, composite lay-ups and varnish. They are made of 100 % coniferous wood and do not have any coarse fibres on the surface. The boards are excellent to mill and emit low quantities of formaldehyde (class E1).
Using the product
The boards must be used only according to use class 1 (restrictions for ambient temperature and humidity) and hazard classes 1 and 2, EN 335-3. The boards must not have direct contact with water during and especially after installation. Any stacking must be done quickly on a pallet or with a sufficient number of crossbeams. Boards must not be stored upright unless floor contact can be ruled out. Under the influence of fluctuating humidity conditions, the boards expand or shrink. However, to a lesser extent than the S-Lux MDFs, which is why a margin for expansion must always be provided for. Use suitable tools for sawing, milling and drilling. MDF Umidax® Noir can be used for structured walls, with a restriction in the load duration category. A corrosion resistant metal fitting, e.g. galvanized steel, must be used in use class 2. Nails or screws must have a distance of at least 8 mm to the edge of the board.

UMIDAX® NOIR MDFs meet the defaults of EN 622-5, option 1, cycle test, whereby the boards are immersed in water, frozen and finally dried. This cycle is repeated three times. After that, the test items are tested for swelling and transverse tensile strength. The boards are checked by our own laboratory daily and have the EU label.
