Pentex™ 25F is a NG-free, small-hole primer. It is intended mainly for use in tunnel rounds, since it is suitable for use with modern charging equipment using either bulk emulsions such as Subtek™ and Civec™ or Orica’s new range of packaged ANFO products, Exan™.
Pentex™ 25F consists of a plastic tube filled with a RDX, Hexogen - based plastic explosive. The RDX gives the product more energy and a higher and more even detonation velocity compared with conventional dynamites. Since Pentex™ 25F does not contain nitroglycerin, it does not cause the headaches associated with the handling of NG products, especially on skin contact.
Pentex™ 25F makes charging work easier, for it contributes to quick and rational handling. The detonator is inserted into the primer quickly and easily. The primer cartridge is then inserted into the charging hose to be deposited at the bottom of the hole during the actual charging sequence.
· Very high detonation rate
· Very high density
· Safe and simple handling
· No additional tool necessary
