Abstract
Thermally conductive polymer (TCP) resin compositions are described, comprising: 50 to 75% matrix polymer (I) comprising styrenic polymers (Γ) such as ABS (acrylonitrile-butadiene-styrene) resins, ASA (acrylonitrile-styrene-acrylate) resins and elastomeric block copolymers of the structure (S-(B/S))-S; and 25 to 50% thermally conductive filler material (II) (D0.1 to 200 μm), consisting of carbonyl iron powder (11-1) in mixture with multi wall carbon nanotubes, silicon carbide, diamond, graphite, aluminosilicates and/or boron nitride (II-2); wherein the volume ratio of (ll-1)/(ll-2) is 15:1 to 0.1:1. Shaped articles made thereof can be used for materials with antistatic finish, electrical and electronic housings, toys and helmet inlays.
