At approximately 180°C, surface graphite begins to exfoliate, progressively increasing as temperature rises, expanding to at least six times its original volume for reliable protection.
Safe to handle with no PPE required, the seals are completely non-toxic, non-fibrous and dust free, using a self-extinguishing PVC binder with added fire retardants throughout.
Totally inert, the seals remain unaffected by moisture, humidity, atmospheric pollution and other common industrial or household chemical substances, ensuring long-term durability and performance.
Fire-only seals feature a flexible PVC nitrile topper, with graphite intumescent from 1mm to 5mm thickness and a 0.5mm three-sided topper, available in various colours and optional self-adhesive tape.
Fire and smoke seals incorporate a cold smoke fin within the same topper construction, while graphite-only intumescent seals suit non-visible applications, supplied in varied sizes with optional self-adhesive tape.
