Effects of wollastonite nano-fibers on ignition time reduction in medium density fiberboard were studied. Nanowollastonite was applied at 5, 10, 15, and 20 g/kg dry weight basis of wood fibers and compared with control specimens. Two application methods of nanowollastonite were used: surface application, and internal application. Specimens of 150×130×9 mm were prepared and the ignition times were measured using two apparatuses: slide fire test apparatus and fixed fire test apparatus. The obtained results indicated that treatments with higher nanowollastonite contents tended to have significant higher ignition times. Internal application of nanowollastonite resulted in an outstanding improvement in the ignition time tested by slide fire test apparatus. It can be concluded that 10% of nanowollastonite gives an ultimate improvement in ignition time.
