Cordtex is a type of detonating cord generally used in mining. It uses an explosive core of pentaerythritol tetranitrate which is inside its plastic coating.

It is commonly the thickness of electrical extension cord and "burns" at 2 km per second. It is used to "daisychain" a sequence of explosives together.

It can also be used in short lengths in simple boobytraps and early warning devices.
