Abstract (en)
[origin: WO02062918A1] The invention concerns a method comprising the combination of a phase-change material in liquid phase (PCM), a texturing agent selected to considerably reduce thermal convection and whereof the viscosity is reversibly reduced, under shearing; the resulting material having a gelled consistency in neutral state, and made flowable under shearing. The phase-change material consists of a mixture of chemical compounds of the family of alkanes: paraffin, waxes, fatty alcohols, fatty acids and the like and the texturing agent is a bulky polymer (hydrocarbon polymers, ester or ether polymers, nixed ester-hydrocarbon polymers) a ionomeric polymer or a di-, tri- or multiple block styrene copolymer (SBS: styrene-butadiene-styrene, SEBS: styrene-ethylene-butadiene-styrene). The invention is useful for thermal insulation of containers or pipes, and particularly for insulating hydrocarbon transmission line).
