ABSTRACT:
The invention relates to base polyolefin compositions, and concentrates thereof adapted to be let down or diluted by addition of further polyolefin, flameproofed by incorporation therein of an organohalo flame-retardant and a metal oxide or sulfide synergist, are rendered resistant to exudation by incorporating therein the combination of an epoxy resin, an elastomeric resin, and a nucleating agent, the epoxy resin being present in an amount of from about 0.01 to about 10 percent, the elastomeric resin being present in an amount of from about 0.1 to about 20 percent, and the nucleating agent being present in an amount of from about 0.1 to about 10 percent and non-fogging molded products obtained thereby.
