«OGRAX-L» fireproof intumescent tape is a fire-resistant elastic roll material used to seal gaps and increase the fire resistance of fire-fighting products.
Principle of operation:
during a fire at temperatures above 180 °C, the material expands to form a fire-resistant coke foam with low thermal conductivity and reliably covers the gaps, preventing the penetration of fire and smoke.
-base: oxidized graphite and rubber
-expansion degree: not less than 20 times
-additional reinforcing layer: calico + adhesive layer
-thickness: 1 - 5 mm
-width: 10 - 1400 mm
-length: 10.5 or 15.9 m
-prevents the penetration of fire and smoke for up to 150 minutes
-service life of at least 25 years (humidity up to 100%, temp range
from -60 to +60°C)
-fire doors and gates
-elevator doors, elevator shafts
-flanged ventilation connections
-ventilation fire-blocking valves
-smoke extraction valves
The material does not emit harmful substances during operation, is resistant to water, gasoline, oils and other petroleum products, and does not form toxic compounds.
