Eastman Neostar FN007 Elastomer
Categories: Polymer; Thermoplastic; Elastomer, TPE; Polyester TPE; Polyester, TP

Material Notes: Neostar FN007 elastomer is the third in Eastman’s series of tough, clear, durable copolyester ethers. Though originally designed for use in the profile and automotive markets, this innovative copolymer has also found use in tubing and packaging applications. Its excellent chemical, heat, and puncture resistance combined with its strength and durability make it a good choice for applications that require flex-crack resistance and a general utility in harsh environments. Neostar FN007 can be injection molded, extruded in blown film or tubing, or extrusion blow molded. The target inherent viscosity of this product is 1.23.
