Elastomer Thermal Protection Materials Containing Aluminosilicate Microspheres

摘要

The effect of the introduction of hollow aluminosilicate microspheres on the efficiency of elastomeric thermal barrier materials based on ethylene-propylene rubber is considered. It is found that the introduction of even small amounts results in a reduction in the density and thermal conductivity of the composition, while maintaining a given level of physical and mechanical properties. Additional treatment of microsphere by element organic modifier allows keep the integrity and improve the structure of the formed coke.
