Composite seal remains flexible between -423 and +500 F. Due to wide temperature capability seal outperforms conventional elastometic seals used in industrial freezers, environmental chambers, refrigerated trucks and railcars, and aircraft doors.
A flexible pile thermal barrier insulator included a plurality of upstanding pile yarns. A generally planar backing section supported the upstanding pile yarns. The backing section included a plurality of filler yarns forming a mesh in a first direction. A plurality of warp yarns were looped around said filler yarns and pile yarns in the backing section and formed a mesh in a second direction. A binder prevented separation of the yarns in the backing section.
Brushlike material insulates variable-width gaps where severe thermal stress is present. Weave-and-tuft strip has low thermal conductivity, working temperature range from -454 to 2,000 F, low load compressibility, and good inhibition of plasma flow.
