Microsphere Effect on the Properties of Elastomer Compositions

Abstract

AbstractIn order to expand the range of products made of elastomeric materials, increase their operational stability and areas of application, new components are being sought. One of the promising directions for solving this problem is the use of microspheres. Many technical problems where weight reduction is required with low thermal conductivity, high strength and volume savings, increased resistance to erosion and corrosive environments can be solved with the use of microspheres. The influence of hollow corundum microspheres grades HCM-S and HCM-L on the rheometric properties of rubbers and the physical and mechanical properties of vulcanizates based on ethylene-propylene diene rubber is considered, and also studies of vulcanizates containing corundum microspheres on the fire and heat-shielding properties based on EPDM rubber are given. -40. It is shown that the investigated microdispersed additives increase the wear resistance of the composites and decrease the specific density of the material. The addition of corundum microspheres to rubber compounds enhances the heat and fire retardant properties of rubbers based on ethylene propylene diene rubber. The degree of influence on the complex of the investigated properties of the introduced corundum microspheres depends on their fractional composition and the nature of the rubber used.KeywordsMicrospheresFire-and-heat protection propertiesPhysical and mechanical propertiesElastomer material
