Sealmaster Intumescent Foam Glazing Tape is a highly compressible and flexible intumescent tape product exhibiting a low pressure intumescent behaviour with a degree of expansion of up to 3-4 times its original volume.
The resistance to thermal erosion is exceptional for a foam tape product allowing it to be used with a very broad range of fire glazing systems.
On exposure to heating the unique chemical formulation allows the product to retain char stability to beyond 900°C, far surpassing other foam glazing tape products currently on the market.
