Envirograf BP/5kg Intumescent Putty – 5kg
The Envirograf BP/5kg Intumescent Putty – 5kg is a flexible passive fire protection sealant designed for filling gaps around metal pipes, cables and electrical trunking. When exposed to heat, the intumescent putty expands to help maintain a secure seal and restrict the spread of fire.
Suitable for filling small holes and joints up to 50mm wide, the Envirograf BP/5kg Intumescent Putty – 5kg remains permanently flexible internally and is unaffected by moisture. Its buff-coloured finish can also be painted over to provide a neater appearance after application.
