Estimating the term…
Thermally-conductive moldable thermoplastic compositions or composites may generally include a plurality of metal-coated filler particles; a plurality of secondary filler particles; and a polymer matrix in admixture with the metal-coated filler particles and the secondary filler particles. The composition or composite may have a thermal conductivity ranging from about 20 Watts per meter-Kelvin to about 35 Watts per meter-Kelvin. Injection molded articles having a moldable thermally-conductive thermoplastic composition or composite can be formed for microelectronics, automotive, avionic, and other heat dissipation applications.
A moldable thermally-conductive thermoplastic composition comprising:
A moldable thermally-conductive thermoplastic composition comprising a polymer matrix admixed with metal containing filler particles including one or more of graphite, perlite, and combinations thereof at least partially coated with metal, the moldable thermally-conductive thermoplastic composition having a thermal conductivity greater than 10 Watts per meter-Kelvin Kelvin and formulated for injection molding applications.
A method of producing a moldable thermally-conductive thermoplastic composition comprising a plurality of metal-coated filler particles and a polymer matrix in admixture with the metal-coated filler particles and having a thermal conductivity of at least 10 Watts per meter Kelvin, the method comprising mixing the metal-coated filler particles in the polymer matrix such that the amount of metal-coated filler particles is at least about 50% volume of the total composition.
