Low-d. polyethylene was modified with antistatic additives and flame retardants by extrusion and hot pressing, and tested for elec. and thermal properties. Flammability tests were also carried out. The corn. antistatic Pebax admixture was an effective additive. The addn. of Al and Mg hydroxides delayed the ignition of polyethylene. A synergy between hydroxides, red P and expanded graphite was obsd.
