PURPOSE:To provide the titled compsn. having excellent electrical conductivity, surface appearance, moldability and mechanical properties, consisting of a thermoplastic resin, a decabromodiphenyl flame retarder, a flame retardance synergist and a bundled stainless steel fiber. CONSTITUTION:1,000-50,000 stainless steel fibers having a diameter of 2-20mu and contg. 1-20wt% vinyl acetate copolymer deposited thereon are bundled together and then cut into pieces of 2.5-7.5mm in length to obtain a bundled stainless steel fiber (A). 0-120pts.wt. decabromodiphenyl flame retarder (e.g. decabromodiphenyl ether) and 0-40pts.wt. flame retardance synergist (e.g. Sb2O3) are mixed with 100pts.wt. thermoplastic resin (e.g. ABS resin). The mixture is pelletized. 1-15pts.wt. component A is melt-kneaded with 100pts.wt. pellet so that the average fiber length is kept 0.5-2.0mm. |
