Abstract
Flame retardant, conductive plastic molding compositions are provided in granular form comprising a thermoplastic resinous matrix through which are distributed fine, solid anisometrically shaped metallic particles in amounts totalling between about 12% and about 40% by volume. The formulation of said matrix is such that it contains at least about 24% by weight of chlorine derived primarily from vinyl chloride resins having K values between about 45 and about 70, and it also contains from about 3% to about 15% by weight of balanced lubricant/stabilizer combinations. Said anisometrically shaped metallic particles typically have aspect ratios of over about 10 to 1 and a minimum characteristic dimension of over 1 micron and are preferably composed almost entirely of conductive metal.
