THERMOPLASTIC RESIN COMPOSITION FOR CLEANING

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition for cleaning capable of efficiently performing a cleaning work of scorched resins and carbonized materials attached on a screw and the inner wall surface of a mold-processing machine in a short time, without disassembling the mold-processing machine or taking out the screw for grinding work and without damaging the screw or the cylinder. SOLUTION: This thermoplastic resin composition for cleaning is obtained by blending 100 pts. wt. thermoplastic resin with 1-150 pts. wt. amino-based resin powder and 1-250 pts. wt. un-vulcanized synthetic rubber or natural rubber. Pellets are made from the same and a method for cleaning is to use them. COPYRIGHT: (C)2005,JPO&NCIPI
