Eastman 18DOA Polyethylene

Polyethylene 18DOA is a low density formulation suggested for the production of closures where a high melt index material is needed to meet shrinkage requirements and fast molding cycles. It molds with unusual ease and is suggested for large, thin-walled items where stress-crack resistance is not a primary requirement. Polyethylene 18DOA can be used as a base for color concentrates. This formula complies with FDA regulations at 21 CFR177.1520 (c)(2.2) for use in articles for packing and holding food during cooking. Users must make their own determination that their use of this product is safe, legal, and technically suitable for their intended applications.

Unless otherwise noted, all tests are run at 23°C and 50% RH.

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.
