Abstract
The present invention relates to a lead-free, non-toxic and arc resistant composite material having a thermosetting polymer, at least one heavy particulate filler, at least one light particulate filler and, optionally, at least one arc resistant filler. The composite material may be utilized in manufacturing articles used in radiation shielding and other applications where arc resistant and dielectric strength are desired.
