FR plywood is treated using chemicals that act as a physical barrier to fire and prevent the timber from oxidizing, making it hard to burn.
FR plywood will char when on fire but will not burn, significantly reducing the progress of a fire. FR plywood achieves reduced flammability by lowering the rate at which flames travel and subsequently slowing down combustion.
The chemicals used to treat FR plywood also reduce the rate at which heat is released from the product during a fire by altering the vapours released in the combustion process, making the flames less volatile.
It is commonly used in public places, where the risk of fire has to be reduced such as for making the woodwork in the kitchens ent in fire resistance.of large restaurants, or for the interior woodwork done in public theatres and halls, and the wood used in the railway compartments of our trains. It can also be used in homes and offices, for car interiors, and any other such places where the risk and spread of the fire have to be reduced.
