PETN (Penta Erythritol Tetra Nitrate)

Penta Erythritol Tetra Nitrate (PETN) is a white colour crystalline material. The crystals are short and hexagonal with minimum elongates and free from needle shaped crystals, dust and visible impurities. PETN is used independently as a high explosive, as the explosive core for detonating cords or as an ingredient of composite explosives.
