AP A New Voice	posted December 30, 1999 06:44 PM How heat and shock sensitive is HMTD really? Much more than Acetone-Peroxide?
darcey Frequent Poster	posted December 30, 1999 09:49 PM im not really sure how heat and shock sensitive HMTD really is but it will detonate if it comes in contact with a flame or even a hot piece of wire (i usally use a sparkler for fuse if i don't have any pro blasting fuse and it works fine). I once got a tablespoon of HMTD in a soft paper casing and taped it to the bottom of a brick, i rigged up a little dropping device (stick and string) and set it up so the brick would fall whan i tugged the string. The brick weight was 2kg and i dropped it from a height of 30cm. It went off with a large bang. So it put it bluntly, its very heat and shock sensitive but if your careful you will be fine. I don't really fuck with AP that much (only made it once) i don't rally like it so i could really tell you which one is more sensitive. NBK2000 or Mega would know, ask them.
Ho ju Moderator	posted December 30, 1999 10:21 PM not to detract from the question about HMTD... if you did the same test (you know with the brick) how big would the weight have to be to do that to AP say if you hoisted it up 3 feet in the air? ------------------ -Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

HMTD Factory Frequent Poster	posted December 31, 1999 01:26 AM They are very very touchy, I hardly lose one eye(hit 5mm away from my cornea) to them, they are totally not what you think, they are like going off whenever they want, so sensitive. I hammered some using just little force, I heard cracks from a few crystal. There is a test for explosives around their shock sensitivity, by dropping them from height, see form how high will they explode when dropped, not widely avaliable data.
AP A New Voice	posted January 01, 2000 09:15 AM NBK2000 can you say me how much more HMTD shock and friction sensitive is than AP?
dlwdaw Frequent Poster	posted January 01, 2000 12:18 PM AP is more friction sensitive than HMTD. not much but there is a difference. also AP ignites faster than HMTD, if you lay a very thin layer of each on a pice of paper, AP will go off first, then HMTD. ------------------ ~dlwdaw "Tick, tick, tick, tick ...Haa!

AP A New Voice	posted January 01, 2000 07:16 PM I only used AP and I want to know which one is better and more safety.
nbk2000 Moderator	posted January 01, 2000 08:00 PM I've never uses HMTD, so I can't say from personal experience how sensitive it is compared to AP. But, I never had an accidental explosion with AP (and I wasn't too careful with it either) so I would say AP is OK. Just treat all primary explosives with care and you'll be alright. Heavy leather gloves will stop the small particles and prevent flash burns too. A good habit to get into is to not hold primary explosive containers with your hand. Use kitchen tongs with rubberized tips instead. Small amounts of explosives only have a blast effect within a couple of inches. So if your hand is 6 inches away from an ounce of HMTD or AP when it detonates, you'll probably have some shrapnel in your hand, but at least you'll still have a hand. I carried detonators by the fuse, not touching it until actually placing it in the charge. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
