THERMAL INVESTIGATION OF FLAME RETARDER CONTAINING PET


Dorottya Nagy, Balázs Ádám and György Czél

Abstract

PET (polyethylene terephthalate) was modified with a flame retardant (FR) additive, which is melamine derivative (MC). The FR additive was mixed to the original PET material in different quantities. Modified PET samples were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). By TG technique the dessolvation and its nature can be measured. With DSC the changes in enthalpy can be investigated, like melting and formation of crystallite fractions. The TG measures were performed in inert (nitrogen) and in oxygen atmosphere, so the effect of oxygen was investigated. In this paper the materials with different doses of FR additive were compared with each other, and conclusion was made from experiments.
