1. Product Description & Fire Chemistry
Cuzi Particle Board Fire Retardant (FR) Chipboard is manufactured by introducing non-halogenated, intumescent ammonium polyphosphate and aluminum trihydrate minerals directly into the wood fiber matrix prior to 42m continuous thermal pressing. Distinguished by a uniform red core, the board forms a ceramic char barrier when exposed to flame, preventing combustion propagation and smoke emission.
