Cast pentolite bombs-detonators P-500L are intended for use as intermediate detonators for initiating borehole and other charges of low-sensitivity industrial explosives, including water-containing explosives, with a temperature of no more than 85 ° C when charging wells, during blasting operations on the Earth's surface in all climatic regions of the CIS countries at ambient temperatures from -50 up to +50°C.

Cast pentolite detonator sticks P-500L can be used for conducting explosive work when initiated from non-electric initiation systems ("Nonel", "SYNV", "Edilin", etc.) or from a detonating cord DSHE-12, DSHE-6 or other detonating cords with a core mass of at least 6 g/m for explosions in dry and watered wells, including with running water with a pH of 3-7 with a duration of charges in water up to 10 days at a hydrostatic pressure of up to 0.5 MPa (5 kg / cm²), which corresponds to the height of the water column in the well up to 50 m.
