Intumescent Glazing Tape

 RZ intumescent glazing tape(Liking Kerafix Flexpan 200)is a flexible, intumescent material on the basis of exfoliated graphite, unique aggregated material,heat insulation material and so on,it has excellent expansion and thermal properties. RZ intumescent glazing tape(Liking Kerafix Flexpan 200)is a reliable construction material for standard fire rated applications.RZ intumescent glazing tape(Liking Kerafix Flexpan 200)is made from a graphite based, intumescent paper with a self-adhesive coating and a removable backing paper.It can easily be adhered to most clean surface types including glass, metals and plastic laminates.

In case of fire, it can quickly expand to more than 30 times the original volume when it is hot and not fly away. It can completely fill the fire-resistant windows, all the gaps of fire doors, fire prevention, smoke prevention, antivirus, several times of ordinary fireproof seal products, and fireproof windows. The use of fire doors thus forms a strong protective barrier, instantly creating an independent safe space, providing sufficient rescue time of 90 minutes or more in the event of a fire, calmly facing danger and ensuring personal safety.
