PBX9404 1. GENERAL PROPERTIES 1.1 Chemical and Physical Description. Plastic-bonded explosive PBX 9404 is composed of HMX bonded with nitrocellulose (NC) and with tris-beta chloroethylphosphate (CEF) as the plasticizer. A small quantity of diphenylamine (DPA) is added to stabilize the NC. The molding powder is off-white at time of manufacture. As the NC decomposes, the DPA reacts with the decomposition products, and the color changes from white to light blue, dark blue, and finally a yellow-brown. The color can be used to estimat,e the temperature storage history of the powder or molded piece. 1.2 Common Use. PBX 9404 is a high-performance high explosive used in nuclear ordnance. 1.3 Toxicity.‘J The suggested maximum concentration of HMX in air is 1.5 mg/m*. We have no data on NC toxicity. The toxicity of CEF is unknown; DPA is highly toxic if inhaled or absorbed through the skin. 84
2. MANUFACTURE AND PROCUREMENT PBX 9404 2.1 Manufacture. PBX-9404 molding powder is prepared by the water slurry process. A lacquer of NC, CEF, and DPA is prepared in a water-immiscible solvent. This is added to a water slurry containing a bimodal distribution of HMX crystals. During solvent removal by distillation, the plastic, plasticizer, and stabilizer uni- formly coat and agglomerate the HMX crystals in the water phase. The process variables must be closely controlled to produce satisfactory agglomerates, composition, and bulk density. 2.2 Procurement. PBX 9404 is purchased from the US Army Armament Readiness Command under LASL material specification 13Y-103159 Rev. B, dated June 16,197O. 2.3 Shipping.* PBX-9404 molding powder is shipped as a Class A explosive. 2.4 Storage.4 PBX 9404 is stored in Compatibility Group D, Storage Class 1.1. 3.
