OGNEBARIER MTO fire-protective mastic (sealant)
Intumescent sealant for cable penetrations (EIT 120), joints and penetrations of pipes, trays and air ducts (EI 180); cartridge, 3 and 20 kg buckets.

This OGNEBARIER model is designed for pipelines passing through floor slabs and provides a fire resistance rating of EI 180. An intumescent material with an expansion ratio of at least 900 % is housed in a split body with a petal lock, so the collar can also be fitted to a pipe that is already installed. The body comes in two versions — stainless steel or galvanised steel. The collar is suitable for residential, public and industrial facilities, operates at temperatures from −50 to +85 °C and remains functional for 30 years or more.
