TROJAN® NB Universal S
 PRODUCT DESCRIPTION

Properties TROJAN® NB Universal S cast boosters are detonator sensitive, high density, high
 energy molecular explosives designed to optimise initiation of all booster sensitive
 Nominal Density (g/cc) Avg 1.60 explosives. All TROJAN NB Universal S boosters are manufactured with two
 through-tunnels and a blind detonator-well for easy application with either
 Nominal Velocity of detonation (km/sec) 7
 electronic or non-electric detonators or 5.3 g/m minimum strength detonating cord. Detonation Pressure (Kbars) 200
 TROJAN NB Universal boosters are formulated from the highest quality PETN and
 Water Resistance (with no loss of sensitivity) 6 months other high explosive materials ensuring reliability, consistency and durability in all
 Shelf Life Maximum (from date of production) 5 years blasting environments. The fluorescent green container and yellow cap make the
