Dipterrocarpus veneer species impregnated with desired chemicals, glue in un-extended HSC exo-thermic undiluted fire retardant dose incurred phenolic resin, pressed under required specific pressure and temperature to produce the fire safe plywood produce, that being retreated with desire chemicals from top & edges to generate the final fire retardant plywood product, as per strictures of IS-5509. It safe guards the ply from catching fire up to 45 minutes to one hour and take considerable time to get it burnt fully. Fire retardant doors & boars all the same as fire retardant ply, only additional input will be in the first line like…. Dipterrocarpus veneer species and durable hardwood timber’s solid batons impregnated with… balance same.
