What is the inner core material of Cordline detonating cord?

• A. RDX
• B. ANFO
• C. PETN
• D. Dynomite

Answer: (C)

The inner core material of Cordline detonating cord is PETN, which stands for Pentaerythritol Tetranitrate. This chemical compound is significant because it is a high-explosive material known for its velocity of detonation and sensitivity. PETN is commonly used in detonating cords due to its ability to produce a reliable and uniform detonation wave.

When detonated, it creates a powerful shockwave, making it effective for initiating other explosives in mining and construction applications. Its properties allow for precise control over explosive operations, contributing to safety and efficiency in blasting tasks.

In contrast, the other materials listed serve different purposes in the field of explosives. For instance, RDX is another high explosive but not typically used as a core material in detonating cord. ANFO, which stands for Ammonium Nitrate Fuel Oil, is an effective bulk explosive but does not provide the necessary characteristics required for a detonating cord's explosive core. Dynamite, while a well-known explosive, is a different formulation and not utilized in the same way as PETN within detonating cords. Thus, the selection of PETN as the correct answer reflects its role as an industry standard for the inner core of Cordline detonating cord
