Over the last two decades, ISLAND PYROCHEMICAL INDUSTRIES (IPI) has established itself as a reputable supplier of explosive materials for both military and civilian applications.
IPI
explosives are manufactured both to U.S. military specifications and to
foreign military specifications.
IPI’s unmatched experience in shipping explosives worldwide, and in the handling and storage of explosives, have earned it the trust of Load, Assembly and Pack (LAP) Plants and Ordnance Factories worldwide. Our customers can rely on our quality, dependability and superior customer service.
IPI has successfully supplied all the explosives listed below, and others that are not listed on this page. For a complete list of explosives, kindly contact us at office@islandgroup.com..
RDX (Hexogen)
RDX is also known as Hexogen, Cyclonite and Cyclotri-methylene
Trinitramine. This explosive compound has an extremely low volatility.
It is a white solid with a density of 1.806 g/cc and nitrogen content
of 37.84%. Military grade RDX is offered in accordance with MIL-R-398C.
Pure RDX is used in press-loaded projectiles. Cast loading is accomplished
by blending RDX with a relatively low melting point substance. RDX is
also used as a base charge in detonators and in blasting caps.
- Compositions in which RDX is melted with wax are called Composition A (see details below).
- Compositions in which RDX is mixed with TNT are called Composition B (see details below).
- Compositions in which RDX is blended with a non-explosive plasticizer are called Composition C (see details below).
IPI also offers a specific grade of RDX containing 1% desensitizing wax and 0.5% graphite for the oil drilling industry. This grade of RDX is used to produce shaped charges such as open-faced perforators and encapsulated perforators. It may also be used in boosters and explosive cartridges.
HMX (Octogen)
HMX is also known as Octogen. This explosive compound is a white, crystalline
solid with a nitrogen content of 37.84%. Military grade HMX is offered
in accordance with MIL-H-45444B.
HMX is used as an explosive charge when desensitized, as a booster charge in mixtures with TNT (octols), and as an oxidizer in solid rocket and gun propellants.
Two grades of HMX are used for military applications:
- Grade A has a minimum purity of 93% and a 7% maximum RDX content.
- Grade B has a minimum purity of 98% and a 2% maximum RDX content.
IPI also offers an ultra high purity grade of HMX containing 99.8% minimum HMX. This grade is primarily used in the manufacturing of perforators for the oil drilling industry.
Nitroguanidine (Picrite)
Because of the material's low temperature of explosion (about
2,098°C), nitroguanidine is used in triple-base propellants. The addition
of nitroguanidine makes the triple-base propellant practically flashless
and less erosive than nitrocellulose-nitroglycerine (double base propellant)
of comparable force.
Trinitrotoluene
(TNT)
2,4,6-trinitrotoluene has been the most widely used military
explosive since World War I.
The advantages of TNT include low cost, safety in handling, fairly high explosive power, good chemical and thermal stability, compatibility with other explosives, a low melting point favorable for melt casting operations and moderate toxicity.
MIL-T-248C specifies two types of TNT, Type I has a minimum melting point of 80.2°C; Type II has a minimum melting point of 80.4°C.
Composition
A
Composition A explosives consist of a series of formulations
of RDX and a desensitizer. IPI offers Composition A-3, A-4, A-5, and A-6.
Composition
B
Composition B explosives contain various mixtures of RDX and
TNT, in proportions of approximately 60% RDX and 40% TNT. IPI offers Composition
B (MIL-C-401), Composition B3 (MIL-C-45113),
and Composition B4 (MIL-C-46652).
Composition
C
Composition C explosives are a mixture of RDX, a plastic binder
such as polyisobutylene (MIL-P-13298A),
and a plasticizer.
Tritonal
Tritonal is a silvery solid that contains 80% of TNT and 20%
of atomized aluminum powder. Tritonal is used as filler in bombs and shells.
IPI supplies the Aluminum Powder and the TNT required for the production
of tritonal separately. Aluminum Powder is available in accordance with
MIL-A-512 and
MIL-DTL-512C Type III – atomized.
PLASTIC BONDED EXPLOSIVES (PBX)
PBX is a term applied to a variety of explosive mixtures which
have high mechanical strength, good explosive properties, excellent chemical
stability, relative insensitivity to handling and shock, and high thermal
output sensitivity. PBX’s contain a high percentage of basic explosives
such as RDX, HMX, HNS, or PETN in a mixture with a polymeric binder.
IPI manufactures various types of PBX's. Please contact us for additional details.
