Before i attempt to carry this out, i would like to know if MEKP and PETN can be mixed, not in terms of plasticizing but in terms of making PETN fuse sensitive. While in a new thread, i would also like to know what could i use to plasticize PETN or PETN/MEKP mix? I can’t find PIB at all btw.

In my dream i packed a clear fishtank airpump tubing with PETN using a dowel to compress it in there really well, 1 end plugged, other end is prepared immediately before det, by applying few drops of MEKP and inserting a fuse/igniter. Feasible?

Then such improvised detcord could be tested in variety of densities, and tubing diameters. ETN detcord tests results could follow.

Also is there a practical/commercial use of picric acid detcord due to the high brisance? I think it would be really good in cutting apps.

why is this thread tagged "exploding tampon"?

why not try DDNP?

mekp + fuse = very bad the mekp absorbs into the fuse and can det on contact with flame

Im aware of that, thats why i specified in my post that the fuse would be inserted immediately before the blast. Also, dipping the the end of the fuse that is to be inserted into "MEKPETN" in paraffin is a simple solution for that. Use your imagination

MEKP+Tampax?or maybe im just desperately tring to bring responses to this thread
IME DDNP is more sensitive/prone to go off without a warning, but thats could be because my picric from ASA is a bitch and i probably won't attempt again untill i can get phenol.

MEKP is suprisingly insensitive for an energetic peroxide, and other than the smell it could be my favourite primary, second to Ag2C2.

Sorry for the double post


BUT SERIOUSLY?!? I just want to know if there will be any reactions between MEKP and PETN/ETN and I know that both of you people who replied in my thread are knowledgeable! Why does "how do i post images" or "what to do with bunch of roman candles" or "fire water" FFS gets way more replies than this? I promise i will post results / link to youtube vids but please let me know if ill blow my face off by mixing MEKP with PETN ?? I tried with .1g and 1ml of MEKP and they seem to like each other but its been 2 days and such a small scale experiment doesnt necessarily represent what will hapen when i soak a gram or 2. Any possible interactions? PETN was neutralized by dissolving in acetone and adding NaHCO3 solution, MEKP is a bit acidic i presume but ive read that neutralizing peroxides for greater stability is bunch of bullshit since acidic peroxides are more insensitive than they would be in basic ph range.

why not just say... I PLAN TO

and is the concept of a blasting cap THAT HARD TO UNDERSTAND?

it doesn't even need to be metal!
THAT COULD be a blasting cap if you think about it

Is the concept of a self contained blasting cap within detcord THAT HARD TO UNDERSTAND?


Ok thanks for the obvious, but my question is the "inertness" between mekp and petn, and noone is answering that... eh back to roguesci

Diffview, your a retard. The OP is obviously intelligent enough to know what a blasting cap is if hes been making PETN and has made DDNP.

OP, MEKP acts as a solvent and will likely dissolve parrafin somewhat.

I don't think any of us know for sure about incompatibilities between MEKP and PETN. I would say that both neutral they should be ok. BUT if the PETN stays crystalline and doesn't dissolve you have the crystals of PETN surrounded by MEKP... If 2 crystals press together and generate a tremendous pressure in one very very very very small area compressing the liquid MEKP primary... it wouldn't be good. Think sand + MEKP... obviously not as dangerous as that would be, but you get my meaning. Overall I think you should be fine.

You might consider reducing your PETN to as fine a powder as possible before mixing. I can't remember anything about the oxygen balance of either of those explosives, but if they have excess oxygen you might consider dissolving a small bit of some kind of plastic in the MEKP to even out the OB. Since MEKP is a ketone similar to acetone you might see how well polystyrene foam dissolves in MEKP.

Ah, there it is! THANK YOU! good point on MEKP eating paraffin! As far as the oxygen balance i didnt look at in untill now, both PETN and MEKP have negative oxygen balance, so i think that ETN will be a better substitute than PETN having a positive OB to compensate somewhat for MEKP in right proportions, followed by ETN/PETN mixture through the rest of the detcord - which should work pretty well. Also i wouldnt dare to press PETN with MEKP already in the mix just as much as i would not dare to store peroxide based blasting caps... its scarry stuff imo
Thanks for the valuable input.

My PETN synth:
65.8ml of 67.2% HNO3
48.6ml of 98% H2SO4
20g of min. 97% pentaerythritol
mixed acids chilled to -7*C in ice/water/NH4NO3 and pentaerythritol slowly added over the course of 20 minutes. temperature was maintained below 5*C and in last 5minutes of nitration adding pentaerythritol didnt increase the temp so ~6g was dumped in all at once, shortly after my corning magnetic stirrer couldnt create visible vortex (or completley stopped?) in the dense creamy white mixture due to viscosity, so the mixture was stirred with a thermometer for about 5 more minutes. Then, by the recommendation of powerlabs website, mixture was placed in a water bath and heated to approx 45*C for 20mins, and allowed to cool to 30*C for 10mins then dumped into 1L of cold distilled water, decanted and filtered.
Yield is still drying and I will weigh it tomorrow before n after ethanol purification and neutralization. Ill be sure to post the results.

IIRC that powerlabs guy is a douche IRL... or such has been said before... somewhere...

I'd stick to getting synth data from COPAE, roguesci, etc..
