Envirograf BP/1kg Intumescent Putty – 1kg
The Envirograf BP/1kg Intumescent Putty – 1kg is a flexible passive fire protection sealant designed for filling gaps around metal pipes, cables and electrical trunking. When exposed to heat, the intumescent material expands to help seal the opening and restrict the spread of fire.
Suitable for small holes and joints up to 50mm wide, the Envirograf BP/1kg Intumescent Putty – 1kg remains flexible and is unaffected by moisture. Its buff-coloured finish can also be painted over where a neater finished appearance is required.
