Abstract
A conductive thermoset material is provided that provides shielding against electromagnetic radiation. The conductive thermoset material includes an intermixed conductive material dispersed essentially throughout. An antisettling additive is present in the conductive thermoset material to support dispersion, optionally, homogenous dispersion of the conductive material in the resin. The conductive thermoset material is formable into one or more articles. The articles may be transportable and resistant to significant conductivity changes by contact with other surfaces.
Claims7
An article formed with a thermoset electromagnetic interference shielding material said article comprising:
- a thermoset resin;
- a conductive material comprising a mixture of metallic or metallized spheres and metallic or metallized rods, said conductive material dispersed throughout said thermoset resin;
- an antisettling agent added to said thermoset resin, said thermoset resin, said conductive material and said antisettling agent cured in a mold to a shape of the article;
- wherein said article is resistant to fracture due to compressive forces that alter the conductive abilities of said article or that allow both ingress and egress of electromagnetic energy;
- and
- wherein said article is a case or wall with said conductive material homogenously dispersed throughout said article shaped into an enclosure to protect an electronic device from electromagnetic interference (EMI).
