ABSTRACT:
A flexible, non-water absorbing insulation system is described for insulating articles exposed to relatively cold temperatures. This insulation system is especially adapted for insulating delivery or transfer hoses used with cryogenic liquid transfer operations. The insulating material is a thermoplastic sheet-like layer having gas-filled cells to which is attached or bonded to a metallized thermoplastic film. In one embodiment, the metallized thermoplastic material is bonded to the smooth side of the thermoplastic sheet-like material. In another embodiment, metallized thermoplastic material is bonded to both sides of the cell-containing thermoplastic material. The sheet-like insulating material is wrapped at least twice around the hose or article to be insulated. Slits may be cut in the insulating material to make the hose self draining whereby any condensed water can gravity drain once the temperature is above the freezing point of water. The wrapped hose may also be wrapped or encased in a flexible protective material such as leather, fabric, or knitted material.
