Provided is a composite material which is in pellet form and which has particles with a core-shell structure, where the core of the particles has one or more magnetic materials, and the shell is made of silicon dioxide, and the pellet has one or more crosslinkable polyethylene and/or polyethylene-containing copolymers. Also provided is a process for crosslinking polyethylenes, by mixing the composite material, one or more free radical initiators, and at least one polyethylene, and heating the mixture inductively.

Composite material comprising polyethylene and magnetic particles

Composite material comprising&#x2014;one or more heat-activatable free-radical initiators selected from the group consisting of organic peroxides and/or initiators having labile carbon-carbon bonds and particles which have a core-shell structure and the core of which comprises one or more magnetic materials, while the shell comprises silicon dioxide.
