Flame Retardant Polyethylene/Organo-Nanocomposite Foams Cross-Linked by Electron Beam Irradiation

Cross-linking of low-density polyethylene (PE)/organo-nanocomposite blends by electron beam irradiation was studied with the aim of flame retarding foam production by thermal expansion. Flammability and thermal properties of the obtained foams were studied and it was found that relatively low doses up to 42.5 kGy could be used leading to a product with excellent surface appearance and flame retardancy.
