RESIN BLEND FOR MELTING PROCESS, PELLET AND PREPARATION METHOD OF RESIN MOLDED ARTICLE USING THE SAME

摘要

PURPOSE: A Resin blend for melting process is provided to improve the physical properties and the surface properties of a molded resin when melt-processing like extrusion or injection molding, and reduce a processing time and production cost by skipping an additional surface coating step. CONSTITUTION: A resin compound for melting process comprises a first resin and a second resin. The difference of surface energy between the resins is 0.1-35 mN/m. The distribution of molecular weight of the second resin is 1-.25, and the average molecular weight is 30,000-200,000. The resin compound includes 0.1-50 parts by weight second resin, comparison to 100 parts by weight first resin. A pellet comprises a core including the first resin, and a shell including the second resin.
