Abstract
A reliable delay detonator device is disclosed which is thermally and chemically stable and which is also insensitive to mechanical shock and electrostatic charge. The device can be made with differing time delays and can be interconnected with other detonator devices for achieving multiple delay characteristics. A modification of the device is particularly suited to high temperature use. None of the devices contain any primary explosives, the device relying upon pyrotechnic delay materials and secondary explosives.
