Detasheet

Detasheet is a flexible rubberized explosive, somewhat similar to plastic explosives, originally manufactured by DuPont. Its ingredients are PETN with nitrocellulose and a binder.[1]

Properties

It was manufactured in thin flexible sheets with a rubbery texture, technically known as a rubberized explosive and is generally colored either reddish/orange (commercial) or green (military). In use, it is typically cut to shape for precision engineering charges.

Compared to other explosives detasheet is very stable. It is detonated with a blasting cap or primercord but not by small-arms fire, heat, water, pressure, or concussion. Detasheet is relatively expensive compared to other explosives.

Ingredients

Detasheet C, the last and most common version produced, was made up of 63% PETN, 8% nitrocellulose, and 29% acetyl tributyl citrate (ATBC), an organic plasticizer.[1]

Production status

DuPont ceased manufacturing explosives in the 1990s and the trademark is now owned by Ensign-Bickford Aerospace and Defense Company, which now sells a very similar explosive sheet called Primasheet.[1]

Deta Flex

A military variant of Detasheet, called Deta Flex, was manufactured in a single thickness (0.25 inch (6.25 mm)) and olive green colored. Deta Flex contains a higher percentage of PETN (70%).[1]

LX-02-1

A version of Deta Flex is manufactured for Department of Energy research purposes, colored blue and manufactured in various thicknesses. LX-02-1 contains 73.5% PETN, 17.6% butyl rubber, 6.9% ATBC, and 2.0% Cab-o-sil.[1]
