Abstract
A flexible thermal control composite comprising a natural or synthetic polymer and an endotherm dispersed, distributed and suspended within said natural or synthetic polymer i.e. “P”olymer “C”ontaining an “E”ndothermic “A”gent (PCEA). The PCEA can be formed into thin and thick films. It can be drawn, molded, extruded and spun into fibers or all dimensions. It can be formed and chopped into PCEA mulch. Irrespective its final form, the PCEA can be used in insulating, thermoprotecting, heat absorbing applications on the one hand, and heat maintenance applications of all types on the other.
Claims17
A cured flexible thermal control composite comprising boric acid distributed, dispersed and suspended in a polymer having a molecular structure consisting of long chains of mostly linear molecules which prior to curing provide interstitial spaces through which the boric acid is distributed, dispersed and suspended and defines a fixed state therein on curing;
- and
- a thermally conductive substrate adhered to said boric-acid containing polymeric material;
- wherein said boric acid functions as an endothermic agent to effect heat absorption at least in part based on liquefaction or decomposition of said boric acid in said fixed state.
A cured flexible thermal control composite comprising boric acid distributed, dispersed and suspended in a polymer selected from the group consisting of latexes, silicones, polyimides, polyesters, high density polymers, polyamides, polyacrylates, polyetherimides, polyketones, polyphenylene oxides, polyphenylene sulfides, polyphenyl sulfones, acetals, nylons, ABS, polyetherketones, phenolics, polystyrenes, cellulose, polycarbonates, polyethylenes, polypropylenes, acrylenes, polyurethanes, polyvinyls, polyvinylchlorides and mixtures thereof;
- and
- a thermally conductive material adhered to said boric-acid containing polymeric substrate;
- wherein said boric acid functions as an endothermic agent to effect heat absorption at least in part based on liquefaction or decomposition of said boric acid when distributed, dispersed and suspended in said polymer.
