Polymer composition and electrical devices
Patent, 2021

The invention relates to a polymer composition comprising a polymer (a) and a nanoparticle filler (b), wherein the polymer composition comprises a volume percentage (vol. %) of the nanoparticle filler (b), which is Dvol vol. %, and has a center-to-center average distance, in nanometer (nm), in two dimensions (2D) and with a free radius, from one nanoparticle to its nearest nanoparticle neighbour, which is R1st nm, and wherein the polymer composition shows a dependency between said center-to-center average distance to nearest neighbour, R1st, and said volume percentage, Dvol vol. %, which is R1st=E/(Dvol+0.3)+F, wherein Dvol1≤Dvol≤Dvol2, E1≤E≤E2, F1≤F≤F2, and Dvol1 is 0.010 and Dvol2 is 4.4, E1 is 100 and E2 is 280, and F1 is 50 and F2 is 140; an electrical device, e.g. a power cable; and a process for producing an electrical device.
