Gurit® G-PET FR - Fire Retardant Structural Core (v6) - 1

Provisional Datasheet level 1 Gurit® G-PET™ FR FIRE RETARDANT STRUCTURAL CORE ¬ Excellent FST performance, evaluated against ¬ Withstands high process temperatures ¬ Excellent chemical resistance ¬ Good adhesion & mechanical properties ¬ Recyclable ¬ Compatible with all composite processes ¬ Available with Gurit® G-PET™LITE technology Gurit G-PET™FR has been developed in order to meet the growing need for structural core materials with good Fire, Smoke and Toxicity (FST) properties used in Marine, Civil and Transportation markets. It offers a much lower cost FST material compared to high cost / high performance materials such as PMI, PEI or PES foams, addressing lower requirements and needs. ® Starting with Gurit G-PET™, Gurit’s extruded structural PET core, flame retardants are then added to improve FST ® properties. The manufacturing process remains the same as Gurit G-PET™, with slight variation in process settings. ® The material is available in all standard knife cut finishes as well as the new surface heat treatment technology Gurit G® PET™ LITE. Gurit G-PET™ FR is produced in Gurit Tianjin, China. ® Gurit G-PET™ can be processed at high temperatures, withstanding exotherms up to 150⁰C / 300⁰F and offers outstanding fatigue properties, chemical resistance, good adhesion, is a highly consistent extruded foam, it is ideal for wind energy, marine, industrial, and transportation applications. Applicable processing techniques include vacuum infusion, bonding, prepreg, and thermoforming.
