Methyl centralite

The same name was also given to a singlebase propint, designed for small arms, developed by I.C.I. Ltd (Ref 2). The required ballistics for different types of ammo are obtained by surface treating the proplnt grains with methyl centralite, and in some cases, dibutylphthalate. [Pg.206]

Deterrents are used to coat the powder, reducing the initial bum rate, and lowering the burn temperature. Deterrents used include dinitrotoluenes, ethyl centralite, methyl centralite, and phthalates. Inorganic additives such as earth metal salts are added as flash suppressants, and opacifiers such as carbon black can be added to increase the reproducibility of the burn rate [34], Note that several of the listed additive chemicals serve multiple purposes, as summarized in Table 5. Ethyl centralite can be applied as a stabilizer, a plasticizer, and a deterrent. Similarly, dinitrotoluenes can be used as both a plasticizer and a deterrent.

Another common stabilizer is ethyl centralite (Figure 10.3) although methyl centralite is sometimes used.60 Methyl centralite (Sym-dimethyl diphenylurea Centralite II) is also used as a moderant to reduce the burning rate. Ethyl centralite is usually found in double-based propellants. Resorcinol (Figure 10.4) is also used as a stabilizer. [Pg.62]
