Inflammabilité Matières plastiques Polyéthylène basse densité Thermogravimétrie Index. décimale : 668.4 Plastiques, vinyles Résumé : Aluminum hydroxide (ATH), a non-toxic and environmentally friendly flame retardant, was characterized using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). The effect of ATH content on flammability properties of LDPE was also determined using limiting oxygen index (LOI) and smoke density test. The thermal characterization studies showed that the effective temperature range for ATH as a flame retardant is 200 to 350°C. In water release test, it was determined that the release of the water by ATH degradation in ATH increased with increasing temperature. The LOI test showed that the flame retardancy of LDPE increased with increasing ATH content and decreasing ATH particle size. The smoke density test proved that addition of ATH reduced effectively the smoke density of a burning LDPE. It was studied in this paper the effect of ATH particle size on thermal, flammability and viscosity of ATH filled with LDPE.

The effect of TMPTMA addition on electron-beam irradiated LDPE, EVA and blend properties / Maziyar Sabet in INTERNATIONAL POLYMER PROCESSING, Vol. XXVIII, N° 4 (08/2013)  

[article]  inINTERNATIONAL POLYMER PROCESSING > Vol. XXVIII, N° 4 (08/2013) . - p. 386-392 Titre : The effect of TMPTMA addition on electron-beam irradiated LDPE, EVA and blend properties Type de document : texte imprimé Auteurs : Maziyar Sabet, Auteur ; R. M. Savory, Auteur ; A. Hassan, Auteur ; C. T. Ratnam, Auteur Année de publication : 2013 Article en page(s) : p. 386-392 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Alliages polymères -- propriétés mécaniques Allongement à la rupture Copolymère éthylène acétate de vinyle Faisceaux électroniques Irradiation Polyéthylène basse densité Réticulation (polymérisation) Traction (mécanique) Index. décimale : 668.4 Plastiques, vinyles Résumé : In this work low density polyethylene (LDPE) and ethylene vinyl acetate (EVA) were blended in the presence of trimethylol propane trimethylacrylate (TMPTMA) (0 to 6phr). The resultant blends were irradiated with a 3 MeV electron-beam resulting in dosages of 0 to 240kGy using a rhodotron accelerator system. The effect of radiation exposure on the LDPE/EVA/TMPTMA blend properties were investigated with respect to gel content, tensile strength and elongation up to breakage of the blends. The findings indicate that increasing EVA and TMPTMA content yield tighter network structures through enhanced blend crosslinking, which is a direct consequence of irradiation. For pure EVA significant tensile strength improvements are evident as irradiation increases up to 210kGy. Irradiated blends exhibit improved tensile strength and elongation at breakage with respect to pure LDPE and EVA. Volume resistivity (VR) and dielectric constant (DC) of the blends were also studied as a function of EVA content, TMPTMA content and radiation dosage. Increasing EVA and TMPTMA content enhances DC and VR values, whereas, increasing irradiation dosage only effects VR values of the blends. The maximum VR value attained in this work corresponds to a radiation dosage of 170kGy and a blend comprising of 30wt% of EVA.
