Abstract

A thermally conductive polyamide compound is disclosed. The compound comprises a polyamide matrix, boron nitride, and a laser direct structuring additive dispersed in the matrix. The compound can be extruded, molded, calendered, thermoformed, or 3D-printed into a heat dissipating and laser direct structured article.

Claims (13)

1. A thermally conductive polymer compound, comprising:

(a) from about 40 to about 50 weight percent of the polymer compound of polyamide 6,

(b) from about 20 to about 30 weight percent of hexagonal boron nitride,

(c) from about 20 to about 30 weight percent of talc,

(d) from about 2 to about 10 weight percent of a laser direct structuring additive,

(e) from about 7 to about 20 weight percent of glass fiber reinforcing agent,

(f) from about 0.2 to about 2 weight percent of calcium stearate lubricant,

(g) from about 0.1 to about 0.4 weight percent of phenolic anti-oxidant, and

(h) from about 0.1 to about 0.4 tri-aryl phosphite processing stabilizer,

wherein the compound has an in-plane thermal conductivity of more than 2.5 W/mK as measured using ASTM E1461, a plating index greater than 0.7 as measured according to ASTM B568 (using Pocan 7102 at DOW Circuposit 4500 as a plating reference), and an adhesion strength greater than 0.7 N/mm as measured using IPC-TM-650.

2. The compound of claim 1 , wherein the laser direct structuring additive is selected from the group consisting of spinel based metal oxides, organic metal complexes, copper complexes, metal oxides, metal oxide-coated fillers or a combination of them.

3. The compound of claim 1 , further comprising an additive selected from the group consisting of adhesion promoters; biocides; anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers and extenders; flame retardants; glass fibers; smoke suppressants; impact modifiers; initiators; micas; pigments, colorants and dyes; plasticizers; release agents; silanes, titanates and zirconates; slip and anti-blocking agents; ultraviolet light absorbers; viscosity regulators; waxes; catalyst deactivators, and combinations of them.

4. The compound of claim 1 , wherein the hexagonal boron nitride comprises about 20 weight percent of the compound.
