Riteflex® 672 RF-NAT NATURAL

Technical Datasheet | Supplied by Celanese
Riteflex® 672 RF-NAT NATURAL is a natural colored thermoplastic copolyester elastomer with medium modulus. Enables high mechanical strength, flexibility & durability at low temperatures, chemical resistance as well as retention of properties. It offers superior electrical properties and is tough, resilient, easy & economical to process. Exhibits excellent resistance to aging, creep, impact, tear and flex fatigue as well as provides high melting point. It advances weathering resistance and provides softness, no blooming, no color change, UV stabilization & long-term thermal stability. Has wear resistance, excellent surface gloss and good paintability. Is suitable for processing by injection molding and extrusion of profiles, cables, films & fibers. Used in hose & tubing, seals, gaskets, belts, energy absorbing devices, fasteners, film as well as sheet, monofilament, automotive interior parts (dashboards), exterior seating to trampolines, molded chair arms and electrical/electronic connectors. Complies with RoHS, PFOS and PFOA.
