A method consists of adding a material, the fibers of which have a positive electrostatic charge, is added onto a shredded newspaper base either before or after the addition of a pre-coat, consisting of a mixture of an inorganic, non-hygroscopic powder and an antistat.

Abstract: A fire stopping device includes a containment shell with a heat rupturable element and an intumescent filler material arranged in the containment shell. The containment shell is formed of a fire resistant material capable of containing the intumescent material after the rupturable element fails. In addition, the heat rupturable element is designed to fail at a force which is lower than the intumescent filler material expansion force.
