Trenchprime Cast Boosters are high-density molecular explosives designed to produce high detonation pressures for optimum initiation of blasting agents. Trenchprime is specifically designed to accommodate detonators up to 4” (101.5mm) in length. The Trenchprime family of cast boosters is designed to be initiated by non-electric, electric and electronic detonators that are classified as a minimum of #8 strength (450mg or greater PETN) base charge.


  • Trenchprime Cast Boosters detonate in excess of 24,000 ft/sec (7,380 m/sec).
  • Over 230 kb of detonation pressure ensures optimum steady state velocity for blasting agents.
  • Excellent shelf life, highly resistant to water and oil.
  • Optimized initiation energy for all booster sensitive explosives


  • Trenchprime Cast Boosters are manufactured with molecular explosives consisting of PETN and TNT, both of which are sensitive to severe impact, heat or friction. As with all explosives, Trenchprime must be transported, stored and handled with care. Avoid any impact with solid surfaces.
