What is Fire Retardant Medium Density Fibreboard?

Fire retardant FR MDF is medium density fibreboard mixed with flame-retardant additives inside the wood fibre matrix during production, usually marked with red core for easy identification. When exposed to flame, it slows combustion speed, reduces flame spread and suppresses dense smoke, meeting fire safety requirements for public and commercial interior projects. It retains the same smooth surface and machining property of standard MDF.
Key Performance
Flame retardant property, slow flame spread index
Red core identification for fire grade traceability
Good dimensional stability, can be painted, veneered or melamine faced
Low formaldehyde E1 grade available
Suitable for CNC cutting, grooving and moulding for decorative fire-rated panels

Applicationsations
Fire retardant medium density fibreboard is specified for commercial interior projects including hotel wall cladding, school furniture, theatre decoration, office partition panels, airport auxiliary fit-out, exhibition booths and public building decorative components. It is a common fire-safe engineered wood tender material.
