Material Notes:
BMC 2910 incorporates additives which enhance the integral performance of mouldings during and after fire, currently used to mould Boltcaps which are designed to provide protection to the bolted connections in structural steel frames of buildings in the event of fire.Boltcaps are designed to insulate the bolts from temperature of the fire (1000° C) and stop embrittlement and fracture resulting in building collapse.The boltcap also protects against a too rapid cooling and failure of the bolt due to quenching from Firemen's water hoses.Information Provided by Menzolit
