Specific fluid, which is a site of energy conversion, characterized in that it comprises water, strongly scattering mineral powder, in general calcium carbonate, antifreeze and/or a colorant, a surfactant and an antifoam, the powder having a concentration by mass of between 1% and 3% and a median particle size of between 0.8 and 10 &#x3bc;m.

Specific fluid for converting light radiation to heat

The invention concerns a process for the preparation of aqueous suspensions of fluid mineral matter, which are able to be pumped and conveyed by the end user immediately after the filtration stage, possibly followed by a compression, which process comprises filtration in two separate stages. The invention also concerns aqueous suspensions of mineral matter obtained and their uses.

Method for producing aqueous suspensions of mineral fillers, the thus obtained aqueous suspensions of mineral fillers and the use thereof

The invention relates to the use of isotactic polypropylenes of very great fluidity for the preparation of concentrates of fillers which can be used in thermoplastics of the olefinic type such as polypropylene, polyethylene and as a general rule: the polymers used alone or in a mixture, based on ethylenic monomers containing 2 to 6 atoms of carbon polymerized alone or in a mixture. The invention also relates to the concentrates of fillers or master batches prepared from isotactic polypropylenes of very great fluidity. The invention finally relates to the loaded thermoplastic materials obtained with the addition of selected polypropylenes according to the invention, and the industrial products manufactured from, or containing, such thermoplastic materials.

Filler concentrates for use in thermoplastic materials

Method for processing a mineral fillers with a phosphate, said fillers and their uses

Method for the treatment of mineral fillers using organic phosphate treatment agents. Treated mineral fillers obtained by said method and suspension of these treated mineral fillers in polyols. Use of these suspensions in the manufacture of flexible, semirigid, or rigid polyurethane foams used for the manufacture of molded or nonmolded objects.
