METHOD OF MANUFACTURING OLEFIN RESIN PARTICLES AND PRE-EXPANDED PARTICLES

摘要

A method for producing polyolefin resins granules are disclosed, which comprises extruding by using a homodirectional(co-rotating) twin-screw kneading extruder a polyolefin resin from a die nozzle having a diameter of less than 2mm and a discharge amount per hole of 0.5-8 Kg/hr into warm water of 5-90 DEG C which is lower than a temperature of the resin by 140-220 DEG C, and cutting the extrudate with a cutter blade in the warm water. According to this invention, uniformly dispersed compounds are obtained, and switching of a raw resin can be done speedily and economically, and further, resin granules of a desired shape can be produced.
