Cesa™ Fiber Additives Flame Retardants for Synthetic Fibers and Nonwovens Ignitability and flame spread, with or without an additional radiant heat source, are a particular concern for fibers used in indoor applications, or indeed anywhere where human lives could be endangered. They help make fibers more resistant to ignition and control flame propagation, smoke and heat generation. APPLICATIONS Cesa Fiber Additives for flame retardancy are recommended for spun-dyed PP, PET and PA fibers used in applications such as automotive textiles, home and office furnishings, clothing, and carpeting.
