Prva iskra – namenska proizvodnja a.d. is producing all kinds of high explosives whose quality is in line with world standards in this area, GOST, MIL and STANAG, or according to customer’s special requests. PETN is an explosive that is extremely sensitive to impact and friction. Pure PETN is used for manufacturing detonators and detonating cords, as well as plastic explosives. Pharmaceutically pure PETN combined with lactose has its application in pharmaceutical industry.

 

PRODUCT DESCRITPION

 

  • Chemical name: 2,2-Bis(hydroxymethyl)propane-1,3-diol tetranitrate
  • Synonyms: PETN, Penthrite, TЭH, Nitropenta, Pentaerithrityltetranitrat
  • Chemical formula: C5H8N4O12
  • CAS number: 78-11-5

The most common use of PETN is as an explosive with high brisance. It is used in the manufacture of detonating fuse, detonators and plastic explosives. If phlegmatized with a small amount of wax and pressed, it may be used to produce boosters and fillings for smaller caliber projectiles. PETN can also be incorporated into gelatinous, industrial explosives.
