Composite material with EMI shielding properties and process to produce it
摘要
說明書
For example, the one or more dispersants are or comprise at least one maleic anhydride-grafted polymers selected from Polyethylene-graft-maleic anhydride (PE-g-MA), Polypropylene-graft-maleic anhydride (PP-g-MA), Styrene-Ethylene/Butylene-Styrene-maleic anhydride-graft (SEBS-g-MA), and any mixtures thereof.
The Optional Component D being at Least One Filler
The composite material may further comprise from 0 to 50.0 wt. % of component D being at least one filler based on the total weight of the composite material; preferably from 0.1 to 50.0 wt. %, more preferably from 0.2 wt. % to 40.0 wt. %, even more preferably from 0.5 wt. % to 30.0 wt. %, most preferably from 1.0 wt. % to 20 wt. %, even most preferably from 1.5 wt. % to 15.0 wt. %, or from 2.5 wt. % to 12.5 wt. %, or from 5.0 wt. % to 10.0 wt. %, or from 5.0 wt. % to 15 wt. % or from 7.0 wt. % to 15 wt. %.
In an embodiment, the composite material comprises at least 0.1 wt. % of at least one filler, as based on the total weight of the composite material, preferably at least 0.5 wt. %, more preferably at least 1.0 wt. %, even more preferably of at least 1.5 wt. %, most preferably at least 2.5 wt. % and even most preferably at least 5.0 wt. %, or at least 7.0 wt. %.
With preference, the composite material comprises at most 50.0 wt. % or at most 40.0 wt. % of at least one filler, as based on the total weight of the at least one filler, preferably at most 30 wt. %, more preferably at most 20 wt. %, even more preferably at most 15 wt. %, most preferably at most 12.5 wt. % or at most 10.0 wt. %.
