The great technology provided by the best chemical companies. The cross-linkers make the emulsion stiff or rubbery. The explosive will then harden and “lock” itself into a bore hole, fractured hole or up hole. This patented cross-linking technology provides solutions to severe loading conditions. Beyond bulk operations this is an excellent substitution for waxes in packaged products. Cross-linkers can work at ambient temperatures permitting to reduce the size of cooling basin and in this way the dimensions of the whole packaging line. Cartridges produced with cross-linkers do not change their physical characteristics preserving the rubbery structure both in cold and hot weather conditions.
