Plastic Igniter Cord

Plastic Igniter Cord (PIC) is a modern version of quickmatch in which the gunpowder is replaced by a delay composition, consisting essentially of lead dioxide and silicon, while the support material is aluminium or iron wire. A plastic tube encloses the fuse, as in the manner of electrical... 

The rate of burning of plastic igniter cord is primarily governed by the chemical composition of the pyrotechnic and the rate of heat transfer along the support wire. 

Table 10.1 Grades of plastic igniter cord that are commercially available.

PIC Plastic Igniter Cord. A fuse burning with an intense flame progressively along its length. Used for igniting the match attached to shells, etc. Different burning speeds are available from 49 sm to 3.3 sm ... 

Slow igniter cord consists of the same type of plastic incendiary composition extruded not over combustible blackpowder-coated yarns,... 

DuPont—Dow is the primary suppHer of these polymers. There is an estimated 18,000 t of these elastomers used per year. The main uses of CPE are in constmction, automotive, and electrical appHcations. These include power steering hose, electrical cords used in low voltage appHcations (extension cords, ignition wire), pond liners, and as a plastic modifier to improve impact modification.
