APEX Cast Boosters are high detonation pressure explosives and are sensitive to No:6 detonators No:8 detonators and detonating cord APEX Cast Booster upon initiation detonates at a very high velocity and very high temperature.
These qualities together with high density produces good detonation which is sufficient as primers and Boosters they are also used to prime the bore holes with ANFO cartridges and with detonating cord or Detonators/Nonels.
The APEX Cast Boosters can be stored for long period it has very long shelf life APEX Cast Boosters are available in 100gms, 250gms and 400gms.

Twin detonators are useful in down the hole-delay initiation as well as surface initiation in the blast. Twin Detonators are more economical where the blast patterns are repetitive with fixed spacing. It helps in reducing the extra shock tube required for connecting and thus reduces the cost of blast.
Down The Hole detonators are either of 200 ms, 250, 300, 350, 400, 450 and 475 ms and Trunk Line Delays are either 0, 17, 25, 42, 50, 60 ms, 65/67ms.
Twin detonators are available in various combinations viz. 17/200ms, 25/250 ms, 42/475 ms.
