Plastic bonded expls

Paraplex Resin-Bonded Explosive. Usually consists of Paraplex P-43/RDX/Al/Styrene monomer/ Lupersol DDM (as a polymerization catalyst) in the following percentages, viz 6.0/65.0/ 20.0/9.0/0.5. Density 1.65g/cc. The material is mixed and polymerized using the usual procedure for polyester resins and Plastic Bonded Expls (see in this Vol)... [Pg.490]

Green 8c E. James Jr, "Radius of Curvature Effect on Detonation Velocity , 4th-ONRSympDeton (1965), pp 86-91 (The effect of the radius of curvature of the detonation front on the detonation velocity of certain explosives were measured. The results were used to calculate the reaction zone thicknesses for various expls. For example, such thickness was found as 0.064 mm for 85/15-HMX/Viton, using Holston HMX, whereas for the same type plastic-bonded expl made from British Bridgwater HMX it was 0.182mm) 28) C.G.

A number of plastic-bonded expls based on HMX RDX plus polymeric binders has been developed at the Lawrence Livermore Lab, University of California, Livermore. Their props have been compiled by Dobratz (Ref 2)... [Pg.101]

There are two common types of standard press loaded expl compns used in US ammo. One contains waxy binder/desensitizing materials, while the other contains synthetic polymeric materials. Description of plastic bonded expls (PBX) can be found in Vol 8, P60-P77 and are not covered here... [Pg.331]

In the area of expls, information on plastic-bonded expls incorporating silicones can be found in Vol 8, P60-L to P77-L under PBX also, in this Vol see under RIDE , where a uni-temp silicone grease is used as a constituent of this compn. The patent of Stott et al (Ref 21) claims that by using a silicone resin as a binder-fuel, a compressible expl is produced which is insensitive and heat- and solvent-resistant. Thus, asoln of 9lg of Viton (a DuPont Co fluorelastomer — Ref 39, p 921) in 1000ml of acet and 460ml of a soln of 23g Chemlock ... [Pg.330]

Considerable attention has been directed toward development of IR spectral analytical techniques for HMX and related compds. Ref 56 discusses the analysis of alpha, gamma and delta HMX in beta HMX, and presents a detailed literature survey of the properties of HMX polymorphs, and hazard.aspects connected with the transitions between the stable beta form and its polymorphs, Spectrophotometric analysis of HMX in PBX 9404 (a plastic bonded expl) is documented in Ref 53. IR techniques have also been useful in. the determination of the effects of Idw level gamma radiation on the thermal sensitivity of HMX, RDX and HMX—RDX mixts (Ref 61)... [Pg.421]

Cyclotol 75/25 (RDX/TNT 75/25) has both good and bad properties as measured by the Susan test (Fig 3). The threshold velocity for reaction is probably about 180ft/sec (55m/sec), which is rather typical of the TNT-bonded cast expls and higher than most plastic-bonded expls. [Pg.483]

PBX. An acronym for Plastic Bonded Explosive. A term applied to a variety of expl mixts which are characterized by high mechanical strength (above 10,000psi compressive strength), good expl properties (usually > 780Qm/sec deton vel),... [Pg.537]

PB—RDX (Plastic-Bonded RDX) was developed by Los Alamos Scientific Laboratory of the University of California for use as a mechanical strength expl. It consisted of RDX 90, polystyrene 8.5 dioctylphthalate 1.5% (Ref 70,... [Pg.158]

HNS has a uniquely small critical diam ( 0.020 inch), i s practically insensitive to electrostatic spark, is less sensitive to impact than Tetryl, is radiation resistant, and is the only commercially available expl meeting the expl sensitivity requirements of the Fuze Design Safety Criteria of all three services (Ref 8) Uses HNS is used as a heat-resistant booster expl. It is sufficiently insensitive to heat, impact, and electrostatic spark to be used in mild detonating fuse (MDF) end couplers St end boosters. It may find application in leads and in plastic-bonded HE s... [Pg.351]

Tetryl has been used as an expl since 1906. In the early part of this century it was frequently used as the base charge of blasting caps but is now replaced by PETN or RDX. During WWII it was used as a component of expl mixts (see Tetrytols in this Vol). Tetryl is still used in military boosters and leads (the expl component of a fuze between the detonator and booster), but even here it is being replaced by plastic-bonded or waxed RDX and HMX expls. A widely used shock sensitivity test employs Tetryl as the donor charge (see Shock Sensitivity of ... [Pg.642]

In one of the more extensive programs, Urizar et al (Ref 98) exposed a number of secondary expl compds and mUts to two fluence levels (10 n/cm with 5 x 10 R and 3 x 0 n/cm with 2 x 10 R) in the Ground Test Reactor at Convair, Fort Worth, Texas. The expl materials involved were TNT, Tetryl, NC, RDX, HMX, PETN, Composition B, and three plastic-bonded... [Pg.38]
