The present invention relates to the production of watertight, non-explosive detonators for explosions and the like. Operations and in particular to safety detonators in which the core of self-combustible material surrounded by the shell is designed as a coherent rod made of a non-porous mass, the rem being made of the xJiSJtmapxKXlxxKkEX mass, which is in a thermoplastic state, is manufactured by means of the injection molding process.

Although safety igniter are usually made by wrapping a strip-shaped coated without the cord resulting 3chwarzpulvermasse in a suitable Tfxtilhtllle _f drawing through a Mse and applying water-resistant coatings are auph already igniter with a continuous water-resistant core, which after the spraying process from a thermoplastic Kisohurg of with Iiitroglycerin is made of gelatinized nitrocellulose and suitable powdery oxidizing and reducing agents, variously proposed to prevent the penetration of water

The nitrogen content of the nitropolyatyrenes is advantageously between 11.0 and 14.4

It has also been found that ingredients containing xennine do not tend to cause hardening of plasticized kitropolyetyrenes, furthermore that the old class, for example, due to the barium perozyd-related antiquity, has no influence on sitropolyetyrene, and that powder coatings, which are called silica or silica, Contain calcium perchlorate, resulting in richer, burning security thunders, if these compounds are evenly distributed in plasticized nitro-polyatyrene instead of plasticized nitro-cellulose or methyl methacrylate.

In the event that the core of the watertight detonator is closed, it can be grounded with a central metal wire embedded in the length or with a thread made of plastic or textile material .
