  • Method for extruding a polymer in the presence of water
    Patent number: 9579838
    Abstract: The invention relates to a method for converting a polycondensed elastomeric thermoplastic polymer, including a step of extruding the polycondensed elastomeric thermoplastic polymer in the presence of water. The polycondensed elastomeric thermoplastic polymer is in particular chosen from copolymer block amides, copolyethers or copolyester block urethanes, copolyether block esters and the mixtures thereof, and is preferably a copolyether block amide.
    Type: Grant

  • Method for filtration of a liquid, in particular for the filtration of beer, using a filter aid
    Publication number: 20040026338
    Abstract: The invention relates to a filter aid for filtering a liquid, such as beer, in a filtration device working on a defined filtration velocity, said filter aid consists essentially of particles of a material A, wherein the flotation velocity UoA is measured as Formula (I): wherein dA is the diameter of the particle, &mgr; is the viscosity of the fluid, r is the density of the fluid and &rgr;a is the density of the particle. The invention further relates to the use of said filter aid as a precoating material in a candle filtration device and to the candle filtration device comprising a number of candles provided with a precoat consisting essentially of the filter aid according to the invention and to a filtrated liquid, for example alcohol and more in particular beer, obtained via a filtration method using a candle filtration device.
