Which explosive component is most sensitive to shock and friction?

The explosive component that is most sensitive to shock and friction is PETN (Pentaerythritol Tetranitrate). This compound is known for its high sensitivity, making it more likely to detonate when subjected to physical force such as shock or friction. PETN is often used in military applications, particularly as a booster for other explosives, due to its performance characteristics.

The sensitivity of PETN compared to other common explosives like RDX, TNT, or ANFO is significant in terms of handling and safety protocols. While RDX and TNT are also sensitive explosives, they are not as sensitive to mechanical stimuli like shock and friction as PETN. ANFO (Ammonium Nitrate Fuel Oil) is generally considered less sensitive and requires a high-energy initiator for detonation, making it suitable for bulk applications without significant handling risks associated with shock and friction. Understanding these sensitivity differences is crucial for maintaining safety standards while working with explosives.
