OGRAX-PPU spray-applied fire protection (polyurethane foam)
Two-component spray polyurethane foam for structural fire and cryogenic protection of steel structures; ratings of 60, 90, 120 and 150 minutes.

OGRAX-LTU differs from OGRAX-L tape in its technology: it is an extruded material based on oxidised graphite and PVC with adhesive transfer tape, with a smooth or ribbed surface. Intumescence starts at +180 °C; for 90 minutes the tape prevents the passage of gases, flame and smoke. Applications include fire doors, partitions, dampers, air duct flanges, lift shafts, safes, collars and reinforced concrete fire-rated structures. The operating range is from −60 to +60 °C at humidity up to 100%.
