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. Our Cesa™ Fiber Additives portfolio includes flame retardant solutions as additive concentrates which are incorporated into the polymer during the spin-dyeing process. 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.
