Fire-safe and water-tight rubber seal compound 05 Jul 2018

Sealing gaskets used in underground construction must be fastened tightly to achieve the required seal. This accelerates wear and tear, which compromises the function of the seal. In the event of a fire where gas or smoke may be released, the consequences can be catastrophic.

Nofirno can be cut to any size

Seals against water

To prevent this, Beele Engineering has developed a new type of gasket using high-quality Nofirno rubber that can be used in environments with temperatures ranging from -50^oC to +180^oC. Once fastened, a lasting seal is created that can withstand pressures of up to 15 bar and regular tightening of bolts is no longer necessary.

As the Nofirno rubber has a high restorative capacity, the gaskets can be reused after the flange has been unscrewed and tightened down again.

The gaskets are available in a wide range of versions and dimensions, including round, square and rectangular, and 1m x 1m gasket sheets which are 5mm or 10 mm thick, from which non-standard shapes can be cut.

As the Nofirno rubber is fire-resistant, and smoke, gas and watertight, the gaskets can be used in environments where fire or water have free range, and are currently being used in fire valves. It has also been approved for drinking water applications. Its UV, ozone and weather-resistant properties make it ideal for outside use too.
