FR230 is suitable for the following service penetrations: single and bunched cables, cable trays/ladders/baskets, non-combustible pipes. Also suitable for cable trunking, combustible pipes, insulated non-combustible pipes, in conjunction with a suitable Nullifire closer device (for example FP302 Intustrap or FS709 HP). Fly-K mortar systems – excellent stealth capabilities and tremendous tactical potential, archived from the original on 2023-03-14 A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) [1] in high-arching ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Mortars are mainly medium calibre weapons. [1] However, mortars both bigger and smaller than this have been made. An example of a smaller mortar is the British 51 mm Light Mortar. The 51mm is carried by just one soldier. It is made up of only a tube and a base plate. A bigger example is the Soviet 2S4 M1975 Tyulpan ( tulip flower) 240mm self-propelled mortar. It is suitable for all kinds of INTERIOR use, but must not to be used outdoors, unless it is protected from water by a roofed area or an additional render coat with a different material.

Fully set within one hour, the compound requires up to 30 days to cure - where it expands to tightly fill the space - before it is fully fire resistant to then preventthe spread of fire and smoke through openings in fire rated walls and floors, including openings formed around building service penetrations.Toys".

Ammunition for mortars generally comes in two main varieties: fin-stabilised and spin-stabilised. Examples of the former have short fins on their posterior portion, which control the path of the bomb in flight. Spin-stabilised mortar bombs rotate as they travel along and leave the mortar tube, which stabilises them in much the same way as a rifle bullet. Both types of rounds can be either illumination ( infrared or visible illumination), smoke, high explosive, and training rounds. Mortar bombs are often referred to, incorrectly, as "mortars". [25]Our gypsum based fire resistant mortar creates a perfect seal around cables, pipes and ducts through walls, ceiling and floors. Just add water to the powder and it's simple to use, with no priming necessary and easy application for a smooth finish. Fire Cement is a ready and mixed combination of thermosetting resins and inorganic fillers. When applied and exposed to high temperatures, this combination is capable of healing, which results in a mortar. This mortar is temperature resistant up to 1250ºC. Do not let any unnecessary putty to dry out on the surfaces of the stove or flue pipe. This excessive fire cement can become incredibly difficult to remove later on. All surfaces to which Vitcas Heatproof Mortar is to be applied should be clean and free from grease, dust and dirt.
