ABSTRACT:
This invention provides an electrically conductive polyolefin composition which contains a balanced mixture of fillers which increase the extrudability of the polyolefin composition into shaped articles of improved flex strength and resistance to shrinkage. The amounts of constituents of compositions of this invention, expressed in parts by weight, are as follows: 100 parts of polypropylene-ethylene copolymer, 15.30 parts of carbon black, 0.25 to 1 part of silica, and 1-10 parts of a fiber-reinforcing agent selected from carbon fibers or mixtures of carbon and glass fibers; and when the fiber-reinforcing agent is a mixture of carbon and glass fibers, then the composition shall contain from 1 to 5 parts of glass fibers and from 1 to 5 parts of carbon fibers.
