US 2026/0269374 A1 · HIGH TEMPERATURE GEL PROCESSED INSULATION COMPOSITE AND ARTICLES MADE THEREFROM

Abstract

Multilayer high-temperature insulative composites that include a gel processed polymer matrix, insulative particles, and additional components are disclosed. In some embodiments, the multilayer high-temperature insulative composite includes at least one insulative composite layer including less than 35 wt % of a gel processed polymer matrix, more than 40 wt % insulative particles, and less than 35 wt % other materials bonded to a second layer to define a diffused bonded portion of the multilayer insulative composite, wherein the diffused bonded portion is defined by an ultrasonic bond. The additional materials include, but are not limited to, an opacifier, an antioxidant, reinforcement fiber(s), and combinations thereof.

Dependent claims

A multilayer insulative composite comprising:

an insulative composite layer comprising greater than about 50 wt % of insulative particles, less than about 35 wt % of a gel processed polymer matrix, and less than about 35 wt % of a combined total of additional components, based on the total weight of the insulative composite layer;
and
a second layer bonded to the insulative composite layer to define a diffused bonded portion of the multilayer insulative composite;
wherein the diffused bonded portion is defined by an ultrasonic bond;
wherein the insulative composite layer has a compressibility less than about 35% at 1 MPa, optionally wherein the second layer includes a second insulative composite layer comprising greater than about 50 wt % of insulative particles, less than about 35 wt % of a gel processed polymer matrix, and less than about 35 wt % of a combined total of additional components based on the total weight of the second insulative composite layer.
