Fire Resistance
KPI ROYALE Fire Retardant Ply is a type of plywood which is treated with special fire-Retardant
chemicals and processes. The addition of fire retardant chemical gives the plywood better fire
resistant qualities such as : opportunity to save life from fire for some Suitable Time.
The main speciality of KPI fire Retardant ply is the addition of preservative chemical by pressure impregnation process which
increases fire resistance and also prevents Borers and termites. Mostly the fireRetardant chemicals decrease the bonding Strength in veneers. Due to pressure
impregnation in ply KPI fire Retardant ply conforms to BWR Grade. A vacuum pressure of 56cm/Hg is applied and fireRetardant solution with preservative is
impregnated with a pressure of 2- 12 kg/cm2 for the required absorption of chemical.
Features
