  • Characteristics
The addition of halogen-free phosphate salts gives the MUF-glued Antivlam chipboard powerful fire-retardant characteristics (European classification B-s1, d0).
Fires in Antivlam go out by themselves and the boards do not continue to glow after the source of heat has been taken away. Furthermore, Antivlam chipboard retains its mechanical strength for a long time in the event of a fire.
Antivlam must be used in service class 1 (limitations in terms of temperature and relative humidity), and is only suitable for biological hazard class 1 of EN Standard 335-3. Direct contact with water is to be avoided at all times.

Antivlam chipboard is suitable for applications where low reactivity to fire and flame spread is essential (stairwells, exit routes, lift shafts, corridors …). Antivlam also offers an excellent solution for applications with higher resistance to fire, such as the core of fire doors or as a firewall.

The fire-retardant chipboard is mainly used in public buildings such as hospitals, airports, retirement homes, theatres, and hotels. … An optional finish with tongue-and-groove joints means that Antivlam is also suitable for use as a subfloor in dry environments. These panels can also be used in vertical applications.

Always use appropriate tools when sawing, milling or drilling Antivlam boards. Fire-retardant products may cause deposits on tools and shorten service life.

Bear in mind that the fire retardants used can influence the gluing and decorative finish of the boards.
