Product Description
Eastman Neostar™ Elastomer FN005 is a tough, clear, durable, general purpose grade copolyester ether. It was designed for use in the profile and automotive markets, but is also used in packaging and tubing applications where toughness and flex-crack resistance are required. Eastman Neostar™ Elastomer FN005 can be used in injection molding and cast film or tubing extrusion applications or in any application that demands strength, durability, and puncture resistance in harsh environments. This copolyester combines toughness, clarity, and flexibility without the addition of plasticizers. Eastman Neostar™ Elastomer FN005 is considered environmentally preferred because of its non-halogenated material composition. The target inherent viscosity of this product is 1.05.

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.
