Abstract
The present invention relates to a composition which can be utilized to induce foaming of a resin or polymeric material in polymer processing machinery. The composition of the present invention includes a blowing agent which decomposes and evolves gases thereby causing the polymeric material to foam. The compositions of the present invention allow for reductions in part weight, cycle times and injection pressure.
