Cyclotol 70/30

Other Names



Cyclotol 70/30, a mixture of 70% RDX and 30% TNT, closely resembles Composition B except for the altered proportions of the components, and is designed as a replacement for Pentolite. It will not, however, have Pentolite’s resistance to flame. Though results of teats are not available, Cyclotol may be anticipated to be more sensitive than Composition B, but considerably less than Pentolite.
