Title
(EN) METALLIC-TONE THERMOPLASTIC RESIN PELLET
(FR) GRANULE DE RÉSINE THERMOPLASTIQUE À TON MÉTALLIQUE
(JA) メタリック調熱可塑性樹脂ペレット
Abstract
(EN)
The present invention provides a thermoplastic resin pellet for obtaining a molded body which has excellent metallic color development, surface smoothness, flow mark-suppressing properties and has a sufficient metallic appearance. The present invention pertains to a metallic-tone thermoplastic resin pellet containing 100 parts by weight of a thermoplastic resin (A), 0.5-10 parts by mass of metallic particles (B), and 0-10 parts by mass of a plate-like, fibrous, and/or granular filler (C), wherein the pellet has a columnar shape in which a cross section perpendicular to the major axis direction is circular or elliptical, the length of the pellet is 0.5-2.8 mm, and the major axis of the cross section is 0.5-2.8 mm.
