Material Notes:
Durastar DS1900HF polymer is a high flow grade of Durastar . Durastar DS1900HF flow lengths are increased 20-40% relative to Durastar DS1000 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 DS1900HF may be used in food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240.Applications/UsesAppliancesFurniture/Furniture trimToys/Sporting goodsFloor careHousewaresWriting instrumentsKey AttributesGood chemical resistanceExcellent flowOutstanding impact resistanceExcellent clarityFast drying timesQuick cycle times
