HIGH TEMPERATURE GEL PROCESSED INSULATION COMPOSITE AND ARTICLES MADE THEREFROM

Abstract

High temperature insulative composites that include a gel processed polymer matrix, insulative particles, and additional components are disclosed. In some embodiments, the high temperature insulative composite includes less than 35 wt % of a gel processed polymer matrix, more than 40 wt % insulative particles, and less than 35 wt % other materials. The additional materials include, but are not limited to, an opacifier, an antioxidant, reinforcement fiber(s), and combinations thereof. Also, the insulative composites have at least one of an average maximum temperature less than about 250° C., a z-strength of at least about 25 N, and a compressibility less than about 35% at 1 MPa. The high temperature insulative composites may be formed into thin, strong shapes, thereby facilitating the ability to fabricate shaped materials suitable for a target application. The insulative composite functions as a protective heat propagation barrier when subjected to a temperature above 300° C.
