Other uses of hexachloroethane are as moth repellent, plasticizer for cellulose esters, anthelmintic in veterinary medicine, mbber accelerator, and as a component in fungicidal and insecticidal formulations. Hexachloroethane reacts with silumin (an aluminum /siUcon alloy) at 483 K to generate an intense white smoke, which is useful in certain pyrotechnics (154). 

Safety fuses are used for the direct ignition of propellants, pyrotechnics, and primary explosives. A safety fuse is composed of a black powder core, three layers of cotton or jute yarn wound around the core, bitumen impregnation, and plastic coating. The burn rate for a safety fuse is usually around 120 + 10 seconds/meter.

Uses. Constituent of alloys with other metals (tin, lead, copper) sulfides used in compounding of rubber and manufacture of pyrotechnics trioxide used as a fire retardant in plastics, rubbers, textiles, and paints chlorides used as coloring agents and as catalysts fluorides used in organic synthesis and pottery manufacmre... 

The rate of burning of plastic igniter cord is primarily governed by the chemical composition of the pyrotechnic and the rate of heat transfer along the support wire. 

The most important application of boron is to make fibers or whiskers of single crystal or ceramic crystal. The addition of boron to metals, alloys, or other solids, imparts resistance to plastic flow, and thereby produces unusual strength in the material. Amorphous boron is used in rockets as an igniter, and in pyrotechnic flares to give green color. Many boron compounds, such as borax, boron hydrides, and boron hahdes, have important commercial applications (see individual compounds).

Cohn, Edit, in Expls Pyrots 6(2), 1973 (Intended as an aid to the design engineer, the reports list 1500 structural material combinations and label them as compatible, incompatible, or marginal. The structural materials include metals, plastics and adhesives, while the expls include primary and secondary expls, propellants and pyrotechnics)... 

Extruders are devices for loading by extrusion (qv) metals, plastics, expls and pyrotechnic compositions. For example, expls such as some Amatols, Explosive D, Compositions A C, etc which cannot be cast-loaded can be loaded by pressing them thru a steel tube by means of a worm screw working inside.

CL-20-based propellant formulations based on NC plasticized with BDNPA/F or EPX (a nitramine plasticizer) are reported to be safe for testing in a 40-caliber gun simulator [211]. Lewis et al. studied a CL-20-based pyrotechnic gas-generating formulation that burns down to produce one or more reaction products that suppress fire [212]. Sato and Kodama studied CL-20 as a base charge for detonators [213] and as a filling of detonation cords [214].
