Material Notes:

Polyethylene 1870A is a low density formulation with excellent flow characteristics for injection molding. It is used for such applications as container closures that require stress-crack resistance. Polyethylene 1870E is used for general-purpose extrusion applications. This formula complies with FDA regulations at 21 CFR 177.1520 (c) (2.2) for cooking applications. Users must make their own determination that their use of this product is safe, legal, and technically suitable for their intended applications.Information from manufacturer data sheet.Eastman Chemical Company sold its polyethylene business to Westlake Chemical Corporation in Dec. 2006. This grade no longer appears in the Westlake product line.
