PREPARATION OF RESIN COMPOSITION FOR SHIELDING ELECTRONIC WAVE

摘要

A polyester resin compsn. for shielding electromagnetic wave is prepd. by: homogeneously mixing the metallic filler and thermoplastic heat-melting adhesives in a heating mixer; heatingmixing the obtd. premixture to first melting temp. of the adhesives component; and admixing 1-60 wt.% of the metallic filler and 0.1-25 wt.% of polyester based heat-melting adhesives with polyester base film w.r.t. the polyester resin. The resin compsn. is useful as housing material of electromagnetic devices.
