摘要:
The invention relates to a process for producing polyurethane foams for wound management wherein a composition containing a polyurethane dispersion and inorganic, cationic coagulants is frothed and dried.
摘要:
The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.

The invention relates to novel microporous coatings and to a process for the production of microporous coatings. A composition comprising an aqueous, anionically hydrophilised polyurethane dispersion (I) and a cationic coagulant (II) is foamed and dried to provide the microporous coating.
摘要:
Novel seed dressing agent formulations comprising of—at least one active agrochemical ingredient for the dressing of seeds, —a dispersion of biologically degradable polyester-polyurethane-polyureas in water whereby the solid content thereof is between 30 and 50 weight %. Said formulation also comprises additives. The invention also relates to a method for the production of a novel seed dressing agent formulation and the utilization thereof for the dressing of seeds.
摘要:
A preferably aqueous dispersion comprises carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from ≧5:95 to ≦75:25. In a process for preparing a dispersion of this kind, carbon nanotubes and graphene platelets are combined so that the ratio by mass of carbon nanotubes to graphene platelets in the dispersion is in a range from ≧5:95 to ≦75:25. The dispersion can be used as a printing ink for producing electrically conductive films. The invention further provides an electrically conductive film comprising carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from ≧5:95 to ≦75:25.
