Product Description
Eastman Neostar™ Elastomer FN006 is the second in Eastman’s series of tough, clear, durable, general purpose grade copolyester ethers. Developed for use in the profile and automotive markets, it can also be used in packaging and tubing applications. Its chemical resistance, flexibility, and toughness make it an ideal choice for applications where strength, durability, and puncture resistance in harsh environments is required. Eastman Neostar™ Elastomer FN006 can be used in injection molding or cast film, blown film, or tubing extrusion applications. This copolyester has a full range of flexibility and memory without the addition of plasticizers. Considered environmentally preferred due to its non-halogenated material composition, it can be incinerated cleanly without the emission of toxic gases. The target inherent viscosity of this product is 1.6.

This product has received a Platinum level Material Health Certificate from the Cradle to Cradle Products Innovation Institute. A Material Health Certificate is awarded to products that meet the Material Health requirements of the multi-attribute Cradle to Cradle CertifiedTM Product Standard. The Cradle to Cradle Products Innovation Institute is a nonprofit organization that administers the publicly available Cradle to Cradle CertifiedTM Product Standard, which provides designers and manufacturers with criteria and requirements for continually improving product materials and manufacturing processes. The Material Health Certificate provides manufacturers with a trusted way to communicate their efforts to identify and replace chemicals of concern in their products.
