The 150g booster is yellow in colour and is designed for use in small blast holes up to 150mm in diameter, typically found in underground, quarry and coal operations. The size and shape of the 150g booster ensures that any Primadet® detonator or equivalent used with the product is fully encapsulated. Detonating cord can also be facilitated as an initiator. Trojan™ cast boosters deliver the driving force required for generating maximum initiating energy and blasting efficiency. They provide reliability, safety and durability for all underground mining, opencast mining and quarry applications. By combining high detonation velocity (7500m/s) with high density (1.6g/cm3), Trojan™ cast boosters optimise detonation pressure (225kbar*) and consistently out perform any other type of commercial boosters. *Pressure = 2.5 x Density x (Velocity)2 x 10.
