Abstract

Methods and systems for an explosive cord are disclosed. An explosive cord may comprise a tubing comprising an inner surface and an outer surface, a reactive material comprising hexanitrostilbene and/or boron potassium nitrate coupled to the inner surface of the tubing, and a hollow or solid core through the center of the explosive cord.

First claim

What is claimed is:

1. A method of manufacturing an explosive cord, comprising:
melting a polymeric material;
extruding the polymeric material through a die;
creating a tubing comprising the polymeric material, the tubing comprising an inner surface and an outer surface, in response to the extruding the polymeric material; and
applying a reactive material to the inner surface of the tubing such that the reactive material defines a hollow core of the explosive cord, wherein the reactive material comprises hexanitrostilbene.

2. The method of claim 1 , wherein the melting the polymeric material comprises a fluoropolymer.

3. The method of claim 2 , wherein the polymeric material comprises poly ethylene chlorotrifluoroethylene.

4. The method of claim 3 , wherein the extruding the polymeric material occurs at a temperature between 250° C. and 280° C.

5. The method of claim 1 , wherein the applying the reactive material to the inner surface of the tubing and the extruding the polymeric material occur simultaneously.
