Both RDX and HMX are substantially desensitized by mixing with TNT to form cyclotols (RDX) and octols (HMX) or by coating with waxes, synthetic polymers, and elastomeric biaders. Most of the RDX made ia the United States is converted to Composition B (60% RDX, 40% TNT, 1 part wax added). Composition A5 (RDX 98.5/stearic acid 1.5) and composition C4 (RDX91/nonexplosive plasticizer) account for the next largest uses. HMX is used as a propellant and ia maximum-performance plastic bonded explosives such as PBX 9401 and PBX N5 and the octols (147—150). [Pg.16]

The organic peroxides and peroxide compositions produced commercially are those that can be manufactured, shipped, stored, and used safely. Organic peroxides can be thermally and mechanically desensitized by wetting or by dilution with suitable solvents, iaert soHd fillers, or iasoluble Hquids (suspension of soHd peroxides ia Hquid plasticizers or water, and emulsions of Hquid peroxides ia water).

Health and Safety. Cinnamyl alcohol has been evaluated by FEMA and given GRAS status (FEMA No. 2294). Two of its esters, cinnamyl cinnamate (FEMA No. 2298) and cinnamyl acetate (FEMA No. 2293), ate also used extensively in flavor and fragrance compositions. Cinnamyl alcohol has also been tested by RIFM (48) and found to be safe for use. There have been reported cases of irritation and several manufacturers market a desensitized alcohol for use in fragrance appHcations. [Pg.176]

After WWII. Composition D—2 which is not an expl, but serves as an emulsifier and desensitizer of expls like HBX-1, consists of wax 84, lecithin 2 NC 14% (Vol 3 of Encycl, p C488-R) Compositions EL—387A and EL—387B, de-... [Pg.157]

Desensitized RDX, one of the constituents in the explosive composition of the standardized military dynamite, was manufactured by coating the SAE 10 engine oil on the RDX in a water slurry at ambient temperatures without a wetting agent. No significant separation at ambient temperature or in 11 months at 65°C... [Pg.507]

It is reported in Refs 42 67 that moderate quantities of waxy materials incorporated with such expl materials as HMX, RDX and PETN do not appreciably affect their initiation sensitivity, but do inhibit propagation to expin. Ref 67 further states that no relationship between the specific and latent heats of the desensitizers and its ability to desensitize could be found, and concludes that the desensitizer cannot be regarded merely as a thermal sink. This is somewhat in conflict with results of work in Ref 91, where it is reported that it has been established firmly that the sensitivity of the RDX compositions decreases with increasing specific heats of the additives, and a solid desensitizer functions primarily by absorbing heat from local regions of initiation including any hot spots which arise from adiabatic compression of occluded gas ...

In order that a wax be accepted for use as a desensitizer in an expl compn, it must not only meet the requirements of Specification Ml L-W-20553, it must also be found acceptable in use tests. Such tests include characterization of a wax in the specific expl compn for incorpora-bility, possibility, sensitivity, physical compatibility, flow properties, cast shrinkage, etc. Examples of Army qualificationworkis contained in Refs 63,87,92 99. The qualification test procedures required by the Navy are spelled out in Ref 95. Specification MIL-W-20553D, paragraph 6.4.2 cites NWS TR-1 and TR-2 for qualification of waxes for Composition B and H-6 and D-2, respectively, and WS 13574, OD 45295 and WS 13564, OD45001 for qualification of Compn A-3...
