A fibrous thermal insulation comprising an intimate blend of A) an effective amount of non-graphitic carbonaceous fibers having an LOI value greater than 40, a percent char value greater than 65, and a thermal conductivity less than 1 BTU hr ft.sup.2 /.degree.F. for providing a synergistic improvement in fire resistance, and B) hollow thermoplastic fibers.

Batting thermal insulation with fire resistant properties

Cryogenic vessels having improved insulation value are prepared by incorporating evacuated tubing within the insulation.

Method of insulating cryogenic vessels

Cryogenic vessel

Disclosed is a concept for covering rigid members with a layer of an energy absorbing material, such as a ceramic foam or glass foam. In a specific application of the invention, the foam layer is used to cover highway structures, such as bridge columns. The objective is to make the highway structure capable of absorbing impact energy from a moving vehicle in the event of a collision.
