Abstract
Zinc berate has been used as a synergistic agent in EVA-Mg(OH)(2) flame ret
ardant (FR) formulations. Solid state NMR of carbon in the residues collect
ed after thermal treatment allows the study of the charring of the flame re
tardant system. The study has shown that polymer fragments are in the char
layer. It is suggested that zinc berate slows the degradation of the polyme
r, creating a vitreous protective residual layer which could act as a physi
cal barrier and a glassy cage for polyethylene chains. (C) 2000 Elsevier Sc
