Thermal Degradation Behavior of Polypropylene and Ethylene Vinyl Acetate Copolymer Treated with Intumescent Flame Retardants Containing Caged Bicyclic Phosphates

Article Preview

Abstract:

Polypropylene (PP) and ethylene vinyl acetate copolymer (EVA) were treated with intumescent flame retardants containing caged bicyclic phosphates. The behavior of thermal degradation of the flame-retarded PP and EVA were studied by TG, DSC, and the FTIR spectra of PP’s residues at different temperature were recorded. In addition, the possible thermal degradation and char formation mechanisms were analyzed and discussed.
