Less sensitive explosives can be initiated by smaller quantities of more sensitive explosives, called primers or detonators, such as blasting caps.
A blasting cap is a small sensitive primary explosive device generally used to detonate a larger, more powerful and less sensitive secondary explosive such as TNT, dynamite, or plastic explosive.

Sensitivity of explosives is the degree to which an explosive can be initiated by impact, heat, or friction. The use of increasingly less sensitive explosive materials to create an escalating chain reaction is known as an explosive train, initiation sequence, or firing train.
Explosives may also be categorized by their sensitivity.

Unlike the thick-cased Mark 83 bombs filled with Composition H6, the AN/M65A1 bombs were thin-skinned and filled with Composition B, an older explosive with greater shock and heat sensitivity.
