==Composition==
The composition of the two most common variants differ according to their use. The '''1A''' (or '''10''') variant is used for [[drilling and blasting|mining]], and is based mostly on crystalline [[Pentaerythritol tetranitrate|PETN]]. The versions '''1AP''' and '''2P''' are formed as hexagonal [[Explosive booster|booster charges]]; a special assembly of PETN and wax inside the charge assures high reliability for [[detonating cord]] or [[detonator]]. The '''H''' (or '''SE''') variant is intended for [[Shock hardening|explosion hardening]].<ref>{{cite web | title=Semtex| website=mondial-defence.com | date=2013-10-05 | url=http://www.mondial-defence.com/images/PDF_Data_Sheets/SEMTEX.pdf | archive-url=https://web.archive.org/web/20131005002550/http://www.mondial-defence.com/images/PDF_Data_Sheets/SEMTEX.pdf | archive-date=2013-10-05 | url-status=dead | access-date=2021-08-16}}</ref>
