Foam for fire protection of building, easily produced in-situ from non-toxic material and avoiding toxic pyrolysis gas

摘要

In-situ foam for protecting buildings from fire is produced from 2 ready-prepared, liquid components containing reactive polysiloxanes. These are discharged from a 2-compartment cartridge pack and a static mixing tube. Within 3 minutes, they expand into the space to be sealed, of any geometry, and react to a reactive-adhesive, elastic cellular plastics.
