Detonating Cord is a linear explosive consisting of a PETN powder wrapped in a flexible plastic outer coating. Manufactured in the EU, EPC-UK is able to supply a comprehensive range of cord weights for a variety of applications.

Detonating cord has a variety of uses in quarrying, mining, civil engineering and other specialist applications. Low strength detonating cords are typically used for the initiation of shock tube in both quarrying and demolition. Higher strength cord is typically used in pre-splitting applications or as a main charge in demolition.

The multilayer construction of the cord ensures a high resistance to tension and abrasion whilst in use.

EPC-UK supply Daveycord and Seicord with the following core loadings and reel lengths:
Daveycord 5g –  200m reel.
Daveycord 12g – 125m reel.
Daveycord 20g, 40g and 70g – 100m reel.
Seicord 100g – 50m reel.
