Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications.
What is Semtex and how does it work?
Explosives such as Semtex, C4 or P4 detonate in a spectacular fashion. The shock wave functions to instantaneously convert the solid explosive into a gaseous form many thousands of times its original volume. This in turn releases energy in the form of light, heat and a devastating shock wave or blast.
What is Semtex explosive made of?
It is a high performance plastic explosive containing a mixture of RDX and PETN bonded by plasticized SBR rubber [25].
Is Semtex the same as C-4?
Semtex is a very powerful explosive device, similar to C4. It was developed in Czechoslovakia. Because of its similarities, it was nicknamed the “Terrorist’s C4” during the Cold War. The explosive is made with mainly RDX and PETN, in addition with numerous binders and stabilizers.
What does Semtex stand for?
plastic explosive
The SEMTEX® plastic explosive was developed at the end of the 1950s, and the serial production started in the 1960s. The title SEMTEX stands for the words SEMTín and EXplosive.
Is Semtex a military explosive?

Composition.
| Compound | RDX |
|---|---|
| Semtex 1A | 4.6% |
| Semtex H | 41.2% |
| Semtex 2P | 22.9% |
What is the most powerful chemical explosive?
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
Does the US military use Semtex?
For its original military use it was manufactured under the name B 1. It has been manufactured under its current name since 1964, [note 1] labeled as SEMTEX 1A, since 1967 as SEMTEX H and since 1987 as SEMTEX 10.
Composition.
| Compound | PETN |
|---|---|
| Semtex 1A | 76% |
| Semtex H | 40.9% |
| Semtex 2P | 58.45% |
When was Semtex created?
1966
Stanislav Brebera, now 77, the scientist son of a bookbinder, invented Semtex in 1966 following orders from the Czech government on behalf of Vietnam.
What does RDX smell like?
It is a white solid without smell or taste, widely used as an explosive. Chemically, it is classified as a nitroamine alongside HMX, which is a more energetic explosive than TNT.

What does C-4 taste like?
C4 Original Drink (Frozen Bombsicle)

Can you eat C-4?
Ingestion of C-4 commonly results in seizures, nausea, and vomiting. Seizures associated with C-4 toxicity respond to standard doses of benzodiazepines.
How do Semtex grenades stick?
It can be made by combining Grenades with Gel. Like the Sticky Bomb, it will not roll, and will instead stick to the first block it touches until it explodes. Like normal Grenades, they will detonate upon touching an enemy, or the player that threw it.
Do Semtex grenades exist?
Semtex Grenades will do 15 impact damage and up to 185 damage after exploding. Unlike Fragmentation Grenades, Semtex Grenades cannot be “cooked” and have a smaller explosion radius.
What does TNT smell like?
Baur recognized this new TNT smell as being similar to that of musk, showing that the scent could be easily and cheaply produced on a large scale. These nitro musks are still used today and are often used as the basis for many perfumes.
Why is nitroglycerin so explosive?
Nitroglycerin, with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
What two chemicals will explode when mixed?
Peroxides (inorganic), when mixed with combustible materials, barium, sodium, and potassium, form explosives that ignite easily. Phosphorus (P), both red and white, forms explosive mixtures with oxidizing agents.
What is the strongest dynamite?
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
What’s more powerful Semtex or C-4?
C-4 is a little bit more powerful than Semtex, but both of them are really good explosives. It would depend of the grade and composition of the explosive, C4 would be powerful under most cases because of the higher RDX component.
Can civilians buy C-4?
C4 can be purchased legally by civilians who have, in the very least, explosives user permits, Tom Crowley with the Bureau of Alcohol, Tobacco and Firearms in Dallas said in an email. Most civilians who buy C4 are in law enforcement, are researchers or are people who use it for training, he said.
What does RDX stand for?
Royal Demolition Explosive
RDX stands for Royal Demolition Explosive, also known as cyclonite, hexogen, and hexahydro-1,3,5-trinitro-1,3,5-triazine. White crystalline solid. RDX is an explosive on its own, and can be combined with other ingredients to make plastic explosives (C-4 contains 91% RDX).
