| | Explosive composition comprising HMX, RDX, or PETN and a high viscosity nitrocellulose binder plasticized with TMETN - ... |
 | | Upon contact with ordinary low viscosity nitrocellulose, TMETN softens the surfaces of the nitrocellulose fibers but is incapable of achieving penetration and complete colloidation of such nitrocellulose and hence is considered unsuitable for the preparation of single and multiple base propellants. |
 | | As increasing proportions of high viscosity nitrocellulose were substituted with low viscosity nitrocellulose, the strength of the processed flexible composition decreased until at complete substitution of high viscosity nitrocellose in the binder, the product became too weak to serve any useful role as a sheet explosive. |
 | | In the determination of the nitrocellulose viscosity aforementioned, the 5/16-inch diameter steel ball shall weigh about 2.025-2.045 grams, the viscosimeter shall consist of a vertically mounted glass tube 14 inches long with an internal diameter of 1 inch immersed to the level of its liquid contents in a constant temperature bath maintained at 25.degree. |
