TECNOFIRE® is our range of versatile lightweight fire protection materials. These materials provide highly effective passive fire protection solutions for a broad range of applications, including composite fabrications & construction gap filling.
TECNOFIRE® materials are classified as INTUMESCENTS, they expand as a result of heat exposure to provide passive fire protection. The material will expand uni-directionally in the z direction by up to 35 times its original thickness when it is exposed to fire or temperatures in excess of 190°C (374°F). The result of this expansion is a thick insulating char. This stabilised char significantly reduces the rate of degradation of underlying materials by insulating them from the heat energy and providing effective fire protection.
The materials are manufactured from high temperature mineral fibres, exfoliating graphite, a small amount of organic binder and, in some cases, active ingredients such as alumina trihydrate (ATH) to enhance performance. The range includes a wide variety of grades and thicknesses to ensure the correct properties and level of expansion for a given application.
TECNOFIRE® has passed a number of fire tests including the ASTM E84-11a test where it achieved a Flame Spread Index (FSI) value of 0 and a Smoke Developed Index (SDI) of 30 or less. The test results mean that the materials have achieved a CLASS A rating in E84, qualifying them for use in Walls & Ceilings and Plenums. In addition, TECNOFIRE® is extensively used in the construction of 30, 60 & 90 minute fire rated doors, which have been Intertek certified (UL10C & NFPA 252) and awarded the Warnock Hersey Mark.
