PRODUCT BULLETIN Cesa™ Flame Retardant Additives Cesa™ Flame Retardant Additives allow manufacturers to design with increased confidence for critical flame and smoke requirements. These more environmentally mindful choices are especially well suited for areas where smoke lessening and toxicity are of concern, such as closed spaces or restricted escape. TARGET APPLICATIONS • Aerospace • Appliances • Automotive, including electric vehicles • Building & construction • Electrical & electronics • Public transportation • Recreational vehicles • Motorcycles, e-bikes, & scooters • Wire & cable IMPACT • Reduce spread of fire and heat release • Limit the amount of smoke allowing people to find their way to safety more easily • Limit toxicity and acidity of gases so people are less likely to be overcome by fumes • Enhance char formation, avoiding droplets which can proliferate fire • Meet regulation and legislation requirements Copyright © 2025, Avient Corporation.

Low Temperature Performance Processing plastics requires low energy input producing favorable life cycle analysis (LCA) benefits and doesn’t create any toxic effluents. Flame Retardant – Increase product safety by including flame retardants to provide halogen-free fire resistant/smoke density/smoke toxicity (FST) and UL94 compliance.

While commodity plastics can typically maintain performance only up to 100°C, and engineering plastics do the same up to 120°C, a high-performance thermoplastic can withstand continuous use temperatures of 230°C while also maintaining low temperature impact. FLAME RETARDANCE: Inherent flame retardant properties allow these materials to pass important flame/smoke/toxicity (FST) tests needed for use in aircraft cabins and railway compartments. For example, PEEK is an excellent candidate for FFF due to its low moisture absorption.
