Effect of Aluminum Alu C and HCM-40 and Yttrium Oxides Y2O3 on the Properties of Composition Materials Based on Perfluorinated «Neofton N» Rubber

Abstract

The properties of two groups of composite materials (CM) based on perfluorinated rubber (FFKM) «Neofton-N» with different contents of trivalent metal oxides: pyrogenic aluminum oxide (Alu C), hollow corundum microspheres (HCM-40) and nanodispersed powder yttrium oxide (Y2O3) were obtained and investigated,. The rheometric characteristics of CM cured with 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane (BOAP) and perfluorohexamethylene-bis-perfluorohexylimidoylamidine (DPIA-65) and their mechanical properties were determined. Thermogravimetric analysis was used to study their temperature parameters. The possibility of obtaining CM with a high level of properties, operable in the temperature range 250–330 °C, has been shown.
