LOW-GLOSS THERMOPLASTIC EXTRUDABLE RESIN COMPOSITION

摘要

PURPOSE: Provided is a low-gloss thermoplastic extrudable resin composition, which has improved impact resistance and is low in gloss variation even under the conditions of extrusion and vacuum molding. CONSTITUTION: The low-gloss thermoplastic resin composition comprises: a base resin consisting of 40-60 wt% of a diene-based rubber component and 40-60 wt% of a styrene-acrylonitrile resin; and 5-20 parts by weight of amorphous inorganic materials based on 100 parts by weight of the base resin. In the resin composition, the diene-based rubber component comprises a large-diameter diene-based rubber component having a particle diameter of 0.2-0.5 micrometers and an ultralarge-diameter diene-based rubber component having a particle diameter of 1.0-3.0 micrometers in a weight ratio of 20-70:30-80.
