Aerogel/PTFE composite insulating material
First Claim
1. A portable electronic device comprisingat least one heat generating component,an enclosure, andan insulating structure located between the heat generating component and the enclosure, the insulating structure comprising an insulating material comprisinggreater than or equal to about 40% wt aerogel particles, andless than or equal to about 60% wt polytetrafluoroethylene (PTFE) particles having a particle size of from about 50 nm to about 600 μ

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.
