Abstract
A material comprising aerogel particles and a polytetrafluoroethylene (PTFE) binder is formed having a thermal conductivity of less than or equal to 25 mW/m K at atmospheric conditions. The material is moldable or formable, having little or no shedding of filler particles, and may be formed into structures such as tapes or composites, for example, by bonding the material between two outer layers. Advantageously, composites may be flexed, stretched, or bent without significant dusting or loss of insulating properties.
Claims16
A composite comprising:
- a material comprising:
- greater than or equal to about 40% wt aerogel particles, and
- less than or equal to about 60% wt polytetrafluoroethylene (PTFE) comprising interconnected PTFE fibrils, having a diameter of about 0.02 μm to 0.1 μm,
- wherein the material is a powder or a putty and the material has a thermal conductivity of less than or equal to 25 mW/m K at atmospheric conditions (298.15 K and 101.3 kPa),
- wherein the material forms a core between 2 layers to form a composite.
