Application
CEPPA is an eco-friendly phosphorous flame retardant, which has been widely applied to high end PET, nylon and FRP to modify their copolymerization retardant ability. Flame-retarded PET chips added with CEPPA has better thermal stability, spinnability and long-lasting flame-retardant ability.
