PURPOSE:To obtain a purging resin composition having high cleaning effect of a system even at a high temperature (>=250 deg.C) and free from foaming, smoke- generation, odor-emission and deterioration of the resin by compounding an organopolysiloxane to a thermoplastic resin. CONSTITUTION:The objective composition is produced by compounding (A) a thermoplastic resin having a melt index of preferably 0.3-5 (e.g., polyethylene) with (B) 1-30 pts.wt., preferably 1-15 pts.wt. of an organopolysiloxane of formula (R is univalent hydrocarbon group; a is positive integer to give the organopolysiloxane having a viscosity of 10-100,000cps at 25 deg.C) and, as necessary, (C) 5-130 pts.wt. of an inorganic filler (e.g., calcium carbonate) and (D) 0.001-6 pts.wt. of an antioxidant (e.g., N,N'-di-2-naphthyl-p-phenylenediamine). |
