The thermal degradation in air of flexible PVC treated with various metal chelates containing Fe, Co, Ni, Cu, or Zn combined with two compounds Al(OH) 3 and Mg(OH) 2 , have been studied by differential thermal analysis and thermogravimetry from ambient temperature to 1023 K. The kinetic parameters were obtained using the equation of Kissinger. Flexible PVC treated with flame-retardants showed a high limiting oxygen index, char yield and a low smoke density rating, maximum smoke density, which indicated that the flame retardance of the treated PVC was improved.

Experiments on the combustion characteristics of untreated wood specimens and also treated ones with boric acid and ammonium pentaborate were carried out using a cone calorimeter according to ISO 5660-1 standard. As a result, comparing to untreated specimen, the fire performance index (FPI) of the specimens treated with boron compounds increased by 1.2 to 2.1 times and the fire growth index (FGI) increased by 1.6 to 8.4%. Also, total smoke release rate (TSR) was 9.0 to 28.3% lower than that of the untreated specimen. It is understood that the test specimens treated with the boron compound produces a carbonized layer with a flame retarding effect. The highest CO concentration, 0.01112%, for the untreated specimen was observed at 418 s, but the specimens treated with boron compound decreased 13.2 to 37.5% compared to untreated specimen. Therefore, wood treated with boron compounds is expected to have lower fire hazards and risks.

In this study, the combustion characteristics of Hinoki Cypress Louver were measured after performing pressure impregnation with aqueous solution of boric acid, borax, and ammonium phosphate. The characteristics measured include ignition time, critical heat flux, and mass loss rate by incident hear flux (25, 30 and 50 kW/m 2 ). The samples used for the test were 100 × 100 × 10 mm, and the 5 min variation for each incident heat flux was measured 3 times. The results show that the ignition time for incident heat flux of 25 kW/m 2 showed a delay effect of 17.4 to 21.3% except for Type C-H. There was no significant difference at 35 and 50 kW/m 2 in the average mass loss rate in Types A-H and D-H, which had lower rates than Type N-H, which was predicted to be higher than that of Type N-H (10.7 kW/m 2 ) by 38.22 to 60.46%. It is thus expected that at the time of initial primary fire, there would be a delay effect against fire spread.
