Smoke plasticized white phosphorus

Plasticized white phosphorus (PWP) was found to be the most promising development for control of the fragmentation of P and pillaring of die smoke. It consists of an intimate mixt of granulated WF in a viscous rubber soin. The material burns more slowly and the particles... 

There are also smoke projectiles which contain PWP (plastic white phosphorus), as, for example the 4.2-inch Mortar Projectile M2 Series, described in Ref 52, pp 4-46 ... 

PWP, Plasticized White Phosphorus. A finely divided WP suspended in gel of rubber and xylene. It is a smoke producing agent vrith side incendiary effects. Its action is similar to WP except that it is slower burning(Ref 36,p 29-41 Ref 54a,p 68). Both PWP and WP are Class C chemical agents Q. A chemical agent of specialized application (Ref 54a,p 68)(Its formula is secret)...
