A FOAMABLE COMPOSITION USING HIGH DENSITY POLYETHYLENE

摘要

A polymeric composition for producing foam in which the polymeric compositio n comprises high density polyethylene, alkenyl aromatic polymer and, optionall y, a resiliency modifier resin. The high density polyethylene is in an amount o f from about 45 to about 90 weight percent of the polymeric composition. The high density polyethylene has a z-average molecular weight, Mz, greater than about 1,000,000. The alkenyl aromatic polymer is in the amount of from about 3 to about 45 weight percent of the polymeric composition. The resiliency modifier resin is in the amount of from 0 to about 40 weight percent of the polymeric composition. The foam is produced in the absence of a significant amount of a stability control agent.
