9mm Fire Rated MDF Board Euro Class B 2440mm x 1220mm (8′ x 4′) FSC®

Description

9mm Fire Rated MDF Board represent a high-density MDF board with a hard, fine and smoothly sanded surface, characterised by extremely low formaldehyde emission. Fibralux MR FR NAF is approved (n° N-18-177) by the Air Resource Board (ARB) as a no-added formaldehyde resin (NAF) MDF board (section 93120.3 of the ATCM ‘Airborne Toxic Control Measure’). This implies that formaldehyde emission is less than 0,04 ppm (90% of tested material), with a maximum of 0.06 ppm for every single measurement. Fibralux MR FR NAF is hardly flammable (ASTM E84 Class A/Class 1 rating for thicknesses 9 – 30 mm and European fire reaction classification B), has a significantly delayed combustion and does not contribute to flame spread. For all available thicknesses (from 6 to 30 mm), Fibralux MR FR NAF is B-s1-d0 certified (EN 13501-1). Fibralux MR FR NAF also meets the criteria required for the MR50/grade 115 designation (ANSI A208.2-2016). It passes the 24-hour submersion test (MR10) and the 6 cycle accelerated aging test (MR30).

Applications

• Fibralux MR FR NAF can be used in applications where MDF panels with a reduced fire reaction, flame spread and smoke development are requested such as:
• finishing of stairway halls
• escape routes or lift shafts in public buildings such as hospitals, airports, retirement homes, theatres, hotels, etc.
• Fibralux MR FR NAF can also be used as part of a building element or system that is aimed at having an increased fire resistance, such as fire doors, ceiling systems or partition walls. The fire resistance certification of such elements or buildings systems in line with local regulations is the responsibility of its producer. The board must be applied in service class 2 (restrictions in temperature and ambient humidity) and can only be used in biological hazard class 1 of EN 335- 3. The boards must be protected from any direct contact with water. They must be stacked flat, on a pallet or using a sufficient number of cross members. Boards should not be stored vertically, unless ground contact can be avoided. The board will expand or shrink under variable humidity conditions.

Note: Like dust from other sheets, materials are harmful. Fire retardant MDF dust can be dangerous if inhaled. So it is recommended to wear dust masks and goggles when working with fire retardant MDF. Besides, you should work in a well-ventilated area.
