Abstract: Polyethylene is basically defined and characterized in ASTM D1248, Standard Specification for Polyethylene Plastics Molding and Extraction Materials. In this document polyethylene is defined as being prepared by the polymerization of no less than 85% ethylene and no less than 95% total olefins. Polyethylenes are separated in ASTM D1248 by their densities. Densities of from 0.910 gm/cc to 0.925 gm/cc are classified as Type 1, low density polyethylene. The range of 0.926 to 0.940 is Type II, medium density polyethylene, 0.941 to 0.959 as Type III and 0.960 up as Type IV, both being called high density polyethylene. This rather arbitrary classification by density has become fundamental in the industry and is reflected in the basic nomenclature of gas distribution piping with medium and high density pipe compounds common terms familiar with the industry.
