Material Notes:
Durastar DS2000 polymer has excellent appearance and is nearly water-clear. Its most outstanding features are toughness, chemical resistance, and excellent processing characteristics. DS2000 has very good toughness as shown by Izod impact resistance. Exposure to aromatic oils often causes crazing or actual fracture of many polymer resins, but DS2000 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. Easy to process, it flows readily and fills intricate molds. Under existing United States Food and Drug Administration (FDA) regulations, Durastar DS2000 may be used in food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240.Applications/UsesPoint of purchase displaysToys/Sporting goodsWriting instrumentsKey AttributesGood chemical resistanceExcellent flowOutstanding impact resistanceExcellent clarityFast drying timesQuick cycle times
