Résumé
The achievement of the composite materials fireproofed by using halogen-free additives is the one of the important requirements in the applications in many domains. In this paper, we present a part of the results acquired by the autors redarding the obtaining of the fireproofed polypropylene and polyamide based composite materials with halogen-free additives.
We analyse the influence of the additives (melamine, teflon) on the physical (melting point, flow index) and electrical (volume resistivity, relative permittivity and loss factor) properties of the obtained composite materials, and it can notice that the influence of the additives content is more important in case of the resistivity and less important for the permittivity and for the loss factor.
