There are visual differences between Semtex and other plastic explosives, too: while C-4 is off-white in colour, Semtex is red or brick-orange. The new explosive was widely exported, notably to the government of North Vietnam, which received 14 tons during the Vietnam War.
What is the difference between Semtex and C-4 explosives?
There are visual differences between Semtex and other plastic explosives, too: while C-4 is off-white in colour, Semtex is red or brick-orange. The new explosive was widely exported, notably to the government of North Vietnam, which received 14 tons during the Vietnam War.
Is Semtex the same as Explosia?
The plant was later renamed to become Explosia a.s., a subsidiary of Synthesia. Semtex was very similar to other plastic explosives, especially C-4, in being highly malleable; but it is usable over a greater temperature range than other plastic explosives, since it stays plastic between −40 and +60 °C. It is also waterproof.
What is Semtex and how does it work?
Semtex takes up the equipment slot. It is comparable to the standard Grenade but with some differences. It is actually a ball of C4 explosive with a timed detonator attached to it, thus, it cannot be cooked, though the timer is shorter than a Frag Grenade's fuse. At close range, the delayed explosion gives opponents time to escape.
Can you use Semtex in MW3?
I used semtex all the time in MW2 & BO, but after using it for a short while in MW3, I'm fairly sure they've nerfed the radius/damage or something. C4 is the only way to go in MW3, since it's blast radius is much higher, it does more damage, and you can choose when to detonate it.
What is the difference between semtex and C-4?
There are visual differences between Semtex and other plastic explosives, too: while C-4 is off-white in colour, Semtex is red or brick-orange. The new explosive was widely exported, notably to the government of North Vietnam, which received 14 tons during the Vietnam War.
What is a semtex?
Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications. Semtex was developed and manufactured in Czechoslovakia, originally under the name B 1 and then under the "Semtex" designation since 1964, labeled as SEMTEX 1A, since 1967 as SEMTEX H, ...
How much semtex was used in the Lockerbie bombing?
As of 2001. [update] , only approximately 10 tons of Semtex were produced annually, almost all for domestic use. On December 21, 1988, 12 ounces (340g) of Semtex brought down a Boeing 747 over Lockerbie, Scotland killing all 259 passengers and crew aboard the aircraft and 11 bystanders on the ground.
When was semtex invented?
Semtex was invented in the late 1950s by Stanislav Brebera and Radim Fukátko, chemists at VCHZ Synthesia, Czechoslovakia (now Czech Republic ). The explosive is named after Semtín, a suburb of Pardubice where the mixture was first manufactured starting in 1964.
Is Semtex a plastic explosive?

Who uses semtex?
It has also been used by Islamic militants in the Middle East and by the Provisional Irish Republican Army (PIRA) and the Irish National Liberation Army in Northern Ireland. Sales declined after Semtex became closely associated with terrorist attacks.
What is the advantage of C4?
A major advantage of C-4 is that it can easily be molded into any desired shape to change the direction of the resulting explosion. C4 has high cutting ability. For example, the complete severing of a 14-inch (36 cm) deep I-beam takes between 1.5 and 2 lb (680 and 910 g) of C4 when properly applied in thin sheets.
How to distinguish C-4 from other C-4?
It is possible to distinguish these sources by analyzing this oil by high-temperature gas chromatography–mass spectrometry. The oil and plasticizer must be separated from the C-4 sample, typically by using a non-polar organic solvent such as pentane followed by solid phase extraction of the plasticizer on silica. This method of analysis is limited by manufacturing variation and methods of distribution.
What is PE4 made of?
The newer PE7 consists of 88.0% RDX, 1.0% DMNB taggant and 11.0% of a binder composed of low molecular mass hydroxyl-terminated polybutadiene, along with an antioxidant and an agent preventing hardening of the binder upon prolonged storage. The PE8 consists of 86.5% RDX, 1.0% DMNB taggant and 12.5% of a binder composed of di (2-ethylhexyl) sebacate thickened with high molecular mass polyisobutylene.
What is the compound C-4?
The Composition C-4 used by the United States Armed Forces contains 91% RDX ("Research Department Explosive", an explosive nitroamine ), bound by a mixture of 5.3% dioctyl sebacate (DOS) or dioctyl adipate (DOA) as the plasticizer (to increase the plasticity of the explosive), thickened with 2.1% polyisobutylene (PIB, a synthetic rubber) as the binder, and 1.6% of a mineral oil often called "process oil." Instead of "process oil," low-viscosity motor oil is used in the manufacture of C-4 for civilian use.
How to make C-4?
The manufacturing process for Composition C-4 specifies that wet RDX and plastic binder are added in a stainless steel mixing kettle. This is called the aqueous slurry-coating process. The kettle is tumbled to obtain a homogeneous mixture. This mixture is wet and must be dried after transfer to drying trays. Drying with forced air for 16 hours at 50 °C to 60 °C is recommended to eliminate excess moisture. : 198
What is PE-4 explosive?
A similar British plastic explosive, also based on RDX but with different plasticizer than Composition C-4, is known as PE-4 (Plastic Explosive No. 4).
How much does a C-4 weigh?
The demolition charge M112 is a rectangular block of Composition C-4 about 2 by 1.5 inches (51 mm × 38 mm) and 11 inches (280 mm) long, weighing 1.25 lb (570 g). The M112 is wrapped in a sometimes olive color Mylar -film container with a pressure-sensitive adhesive tape on one surface.
Which is more powerful, a grenade or a semtex?
Semtex is more powerful than a Frag Grenade: it has a larger explosive radius and the highest explosive damage of any equipment in the game. It is the only grenade that, without Danger Close, can destroy the large gas tanks found in Highrise, Underpass, Overgrown, Derail, and Terminal.
Why is Semtex useful?
The explosive power and blast radius of Semtex also make it useful for rushing classes because it can clear larger areas than a fragmentation grenade and does not ever require cooking.
How much damage does a semtex do in Black Ops 3?
Just like Call of Duty: Black Ops II, Semtex Grenades take 0.6 seconds to prepare and have a two second fuse. Semtex Grenades will do 15 impact damage and up to 185 damage after exploding.
What is a semtex grenade?
It is comparable to the standard Grenade but with some differences. It is actually a ball of C4 explosive with a timed detonator attached to it , thus, it cannot be cooked, though the timer is shorter than a Frag Grenade's fuse. At close range, the delayed explosion gives opponents time to escape. However, the timer counts down while the Semtex is in flight and will explode almost immediately after landing if thrown over long distances. It has a blinking red light and beeps softly, making it easier to spot and avoid. This makes it useful for flushing enemies that have hunkered down, as they may run from cover if a Semtex charge is tossed in proximity, and if they do not run fast enough, they will be killed or severely injured. Because the grenade sticks to the first surface it touches (except glass, which shatters while the Semtex trajectory remains unaffected), it will not bounce and roll past the desired target. This is very useful for accurately sticking the grenade to the Headquarters, narrow platforms, or hillsides. Additionally, it can be stuck to the window sill in front of an enemy rather than actually requiring the grenade go through the window (a throw which, if missed, often means a cooked grenade comes bouncing back at the thrower.) Additionally, Semtex grenades cannot be thrown back at the original sender.
What is a semtex in Call of Duty?
Semtex is a type of lethal grenade containing C4 that sticks to the first surface it touches, including other players, before exploding. It is featured in Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, Call of Duty: Modern Warfare 3, Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified, Call of Duty: Ghosts, ...
How many points does a semtex cost?
The Semtex returns in Zombies in the Town and TranZit submaps of the Green Run map, Die Rise, Nuketown Zombies and Origins. It can be bought off the wall for 250 points, and replaces the grenades players start with. It loses its effectiveness pretty early in the game, losing killing ability sometime after round 10. Until round 10, it has the same killing potential as normal grenades. Due to its relatively low use, it is not recommended to make crawlers.
How much damage does a semtex do?
Semtex takes 0.6 seconds to prepare with a two second fuse. The damage for Semtex is 15 direct damage on stick with 200 damage, and a 4.4 meter lethal blast radius. It seems to be similar to its Call of Duty: Modern Warfare 2 counterpart.
What is a C4 transmission?
Specifically, the vehicles that came with a C4 transmission were the Ford Bronco between 1973 to 1977, and the Ford F-series between 1965 to 1981. Here’s what it looks like:
What is a C4 and C6?
The C4 and C6 are both 3-speed automatic transmissions designed by Ford.
What transmission fluid does a C4 use?

How many gears does a C6 have?
Similarly, the response to questions like how many gears does a C6 transmission has, would be three . What this boils down to, is earlier versions of these transmissions are entirely different from their later iterations.
What is the difference between C-3 and C-2?
The essential difference between Composition C-3 and Composition C-2 is the substitution of 3% tetryl for 3% RDX, which improves the plastic qualities.
How are cartridge strengths obtained?
The different cartridge strengths are obtained by varying the density and grain size of the ingredients. Several manufacturers produce two series of low-density ammonia dynamite, a high- and a low-velocity series. Both series are of lower velocity and density than high-density extra dynamite.
How is the transfer of energy from an explosive to surrounding bodies controlled?
In some cases the useful work that is done is limited only by the energy content of the explosive composition, while in other cases the transfer of energy from the explosive composition to surrounding bodies is controlled to a large degree by the momentum or impulse released by the detonating explosive.
Is C-3 as powerful as TNT?
Composition C-3 is about 1.35 times as powerful as TNT. The melting point of Composition C-3 is 68°C, and it is soluble in acetone. The velocity of detonation is approximate y 26,000 fps. Its color is light brown. As with Composition B, Composition C is no longer being used as a gun projectile main charge. However, some stocks may still be in service with Composition C-3 used as a main charge.
