  • Patent number: 10695702
    Abstract: Blood separation media include a fibrous web formed by 50 to 99 parts by weight of glass microfibers, and 1 to 50 parts by weight of fibrillated fibers; a polymeric, hydrophilic binder; a wetting agent; and a salt. The binder covers at least a part of the glass microfibers, and the web is further impregnated with a wetting agent and it contains a salt which is capable of crenating red blood cells. The pore size of the media is smaller than the average pore size of red blood cells. Compared to conventional separation media, the invention will improve efficiency of the separation of the red blood cells from the plasma and increase the speed and volume of the separated material. The present invention also provides for a decrease in lysing of the red blood cells during the filtration process which gives improved purity of the material.

  • Patent number: 10683617
    Abstract: A wall covering, a method of producing it and a method of covering a wall. The wall covering comprises a planar substrate, such as a nonwoven base substrate, having a front, and a back facing opposite the front. There is a barrier layer on the back of the substrate and an adhesive layer superimposed on the barrier layer. The adhesive layer comprises a first polymer component, a second polymer component, the first polymer component being a non crosslinked polymer and said second polymer component being a crosslinked polymer exhibiting properties of superabsorbency. The adhesive exhibits when exposed to water, a strength sufficient for binding to a wall substrate and a glide resistance low enough for allowing repositioning of the wall cover by sliding the wallcover on the wall without having to lift it up over a period of time of at least 5 minutes.
