DuraStar DS2010
Eastman Chemical Company - Polyester, Thermoplastic

General Information
Product Description

Durastar DS2010 polymer contains a mold release. It has excellent appearance and is nearly water-clear. Its most outstanding features are toughness, chemical resistance, and excellent processing characteristics. DS2010 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 DS2010 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 DS2010 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.

Key Attributes:
- Outstanding Impact Resistance
- Exceptional Clarity
- Fast Drying Times
- Quick Cycle Times
- Chemical Resistance
- Excellent Flow
