Comparison of theory with experimental data for nanoclay-filled TPU/PP blend / Murugasamy Kannan in Industrial & engineering chemistry research, Vol. 51 N° 41 (Octobre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 41 (Octobre 2012) . - pp. 13379-13392 Titre : Comparison of theory with experimental data for nanoclay-filled TPU/PP blend Type de document : texte imprimé Auteurs : Murugasamy Kannan, Auteur ; Suggu Bhagawan, Auteur ; Sabu Thomas, Auteur Année de publication : 2012 Article en page(s) : pp. 13379-13392 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Nanoclay Résumé : The mechanical properties of thermoplastic polyurethane (TPU)/polypropylene (PP) blends were investigated with special reference to the effect of type of polyurethane (ester- or ether-based), blend ratio, compatibilizer, and sequence addition of nanoclay. Tensile strength, stress at different elongations, flexural modulus, and abrasion resistance were analyzed and correlated with morphology. Blends of nanoclay filled thermoplastic polyurethane (TPU)/polypropylene (PP) of various compositions were evaluated by dynamic mechanical properties such as storage modulus (E′), loss modulus (E″), and dissipation factor (tan δ), at a frequency of 10 Hz over a temperature range from −100 to 200 °C. Finally different theoretical models were used to compare the experimental results with theoretical predictions.

Effect of rubber – filler interaction on transport of aromatic liquids through high density polyethylene / ethylene propylene diene terpolymer rubber blends / Anil Kumar P. V. in Industrial & engineering chemistry research, Vol. 51 N° 19 (Mai 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 19 (Mai 2012) . - pp. 6697–6704 Titre : Effect of rubber – filler interaction on transport of aromatic liquids through high density polyethylene / ethylene propylene diene terpolymer rubber blends Type de document : texte imprimé Auteurs : Anil Kumar P. V., Auteur ; K. T. Varughese, Auteur ; Sabu Thomas, Auteur Année de publication : 2012 Article en page(s) : pp. 6697–6704 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : High  density  Transport  process  Filler Résumé : The sorption and transport of four aromatic hydrocarbons through dynamically vulcanized high density polyethylene/ethylene propylene diene terpolymer rubber blends filled with carbon black and that filled with silica at the same loading have been investigated in the temperature range of 28–58 °C by an equilibrium swelling technique . Blends loaded with high abrasion furnace (HAF) black and those with silica of same loading have been used. The silica-incorporated blends sorbed a higher amount of aromatic solvents compared with the HAF filled blends. This has been explained in terms of the differences in the interaction between the filler particles and the blend components. The swelling coefficient, diffusion coefficient, and molar mass between cross-links have been computed to complement the experimental observations.
