PLASTIC COMPOSITE MOULDED BODIES OBTAINABLE BY WELDING IN AN ELECTROMAGNETIC ALTERNATING FIELD

摘要

The invention relates to plastics composite moldings obtainable via welding in an alternating electromagnetic field, in which the weld is obtained with the aid of a plastics material which comprises nano-scale, magnetic oxidic particles, which are composed of aggregated primary particles, and where the primary particles are composed of magnetic metal oxide domains whose diameter is from 2 to 100 nm in a non-magnetic metal oxide matrix or non-magnetic metalloid oxide matrix.
