Eastman Chemical Company - Polyester, Thermoplastic

General Information
Product Description

Durastar DS1910HF polymer is a high flow grade of Durastar that contains a mold release. Durastar DS1910HF flow lengths are increased 20-40% relative to Durastar DS1010 as shown by spiral flow testing. Other outstanding features of Durastar are easily maintained such as excellent appearance and clarity, good physical properties, chemical resistance, and easy processing. This high flow product is especially suited for those applications utilizing thin-walled intricate tools. Under existing United States Food and Drug Administration (FDA) regulations, Durastar DS1910HF may be used in food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240.
This product is certified to ANSI/NSF Standard 51.
