Abstract
A formulation for producing a polymeric material including high-density polyethylene, a chemical blowing agent, and other optional components is described.
Claims29
An insulative cellular non-aromatic polymeric material comprising
- about 50% to about 99.9% by weight of high density polyethylene (HDPE) base resin,
- up to about 1% by weight of a chemical blowing agent,
- up to about 15% by weight of a nucleating agent, and
- a physical blowing agent,
- wherein the insulative cellular non-aromatic polymeric material has a density of about 0.2 g/cm3 to about 0.9 g/cm3.
