摘要:
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.

摘要:
The invention is a stretchable layered fabric laminate which is air impermeable and waterproof while being permeable to water vapor. The stretchable fabric laminate includes a stretchable composite material layer consisting of a hydrophobic protective layer of a porous polymeric material on each side of a layer of hydrophilic water-vapor-permeable synthetic polymer. The composite material layer is laminated to at least one layer of stretchable fabric. The stretchable layered fabric laminate has excellent stretch and recovery properties in both machine and transverse directions, and is useful for the manufacture of form-fitting articles of protective clothing and other end uses.

摘要:
The present invention is directed to gas permeable, oleophobic materials. Preferred materials of the present invention maintain oleophobicity when used in high temperature applications. Most preferable are gas permeable, oleophobic materials that resist penetration by water, and which maintaining these properties upon long-term, high temperature exposure.
