    en.wikipedia.org/wiki/Polymer-bonded_explosive

    Polymer-bonded explosives, also called PBX or plastic-bonded explosives, are explosive materials in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer. PBXs are normally used for explosive materials that are not easily melted into a casting, or are otherwise difficult ...

  9. PFM-1 mine - Wikipedia

    en.wikipedia.org/wiki/PFM-1_mine

    The mine consists of a polyethylene plastic container containing 37 g (1.3 oz) of VS-6D or VS-60D liquid explosive. [1] [3] The two wings of the PFM-1 allow it to glide after being released in the air, then spin, stabilizing it and slowing its descent, similar to maple seeds. [4] [1] The thick wing contains the liquid explosive. [4]
