http://www.ribbands.co.uk/prdpages/C4.htm -nice pix of a guy pulling C4 taffy A high quality, very high velocity military plastic explosive. Our C4 is supplied in bulk drums, in a slightly powdery form. Upon manipulation the material immediately consolidates into a rubbery fully plasticised mass which may be kneaded and pressed into any shape. The material has excellent mechanical and adhesive properties, and may be stretched into long strands without breakage. In its original powdery form the explosive may be poured into charge containers, then pressed into intimate contact with the liner. Substantial price discounts are available on full shipping containers (16 tonnes plus). Please enquire.
