Provided is a flexible heat sink article comprising a base comprising a polymer and a plurality of polymeric protrusions extending away from the base, each protrusion having a major dimension and a minor dimension. The base comprises thermally conductive particles, and the protrusions comprise non-spherical thermally conductive particles substantially aligned in the direction of the major dimension within the protrusions. A thermal interface material may be provided contiguous with the base. Also provided is a flexible heat sink article comprising a base comprising a polymer and having a first surface and a second surface, a plurality of polymeric protrusions extending away from the first surface of the base, each protrusion having a major and a minor dimension, and a metallic layer contiguous with the second surface of the base, wherein the base and the protrusions comprise thermally conductive particles. Also provided is a method of making a flexible heat sink.

The present invention provides a multi-layer tape, comprising: a first adhesive layer comprising a pressure sensitive adhesive; a core layer having an outer surface, the first adhesive layer adhered to at least a portion of the outer surface; and fibrous reinforcing material dispersed within the core layer, the fibrous reinforcing material imparting stretch release properties to the tape. The tape may comprise a second adhesive layer wherein the outer surface comprises a first major surface and a second major surface, the first adhesive layer being adhered to the first major surface, and the second adhesive layer being adhered to the second major surface. A fire retardant may be disposed in any of the first adhesive layer, the second adhesive layer, and the core layer. The tape may be cleanly removable. The fibrous reinforcing material typically comprises substantially continuous viscoelastic microfibers having a yield strength and a tensile break strength, and the tensile break strength is at least about 150% of the yield strength. In another aspect, the tapes of the invention may be formulated to be cleanly removable without including fibrous reinforcing material therein. The invention also provides a method for the manufacture of the foregoing tape as well as an assembly comprising: a substrate; a carpet overlying the substrate; and a tape according to the invention disposed between the carpet and the substrate and adhering the carpet to the substrate.

Cleanly removable tapes and methods for the manufacture thereof

The invention provides an assembly for the control and removal of fluids, the assembly comprising: A fluid control layer having a top side and a bottom side, the top side constructed to facilitate the evaporation or the flow of a fluid disposed thereon; a fire retardant material having a first major surface and a second major surface, the first major surface associated with the bottom side of the fluid control layer, the fire retardant material comprising a polymer; and an adhesive layer associated with the second major surface of the fire retardant material. A fluid management system for aircraft and a method for the use of the system in aircraft are also described.
