The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Disclosed herein are matrices, compositions and methods of making matrices. The matrix comprises a biomolecule and the matrix is a dried, cross-linked foam. The matrix is not lyophilized. The method comprises foaming the composition, crosslinking the composition and drying the composition. Matrices disclosed herein are useful as wound dressings and treating wounds.

The present disclosure relates to an extrusion apparatus comprising: a) a planetary roller extruder; b) a melt pump arranged downstream of the extruder; c) optionally, a fluid feeding equipment; d) a static cooling mixer equipment arranged downstream of the melt pump; e) a foaming equipment arranged downstream of the static cooling mixer equipment. The present disclosure also relates to a process of manufacturing a foamed polymeric composition and uses thereof.

There is disclosed a polymer-based foam composition comprising a polymer and up to 20 M.-% particles of one or more inorganic particulate materials, based on the total weight of the composition, wherein the one or more inorganic particulate materials comprise less than 20 wt.-% Al, calculated as Al.sub.2O.sub.3-content. According to one aspect, the one or more inorganic particulate materials comprise phyllosilicates. Also part of the present invention is the use of such polymer-based foam compositions and their method of production.

The present application relates to a supercritical fluid injection foaming polylactide foam material and a preparation method therefor. The method includes: first obtaining a surface-modified cellulose nanofiber aqueous solution; then melting and blending the cellulose nanofiber aqueous solution and a polylactide twice; passing same through extrusion, cooling under water, and granulation so as to obtain a polylactide/cellulose nanofiber composite material; then plasticizing and melting the polylactide/cellulose nanofiber composite material in a microporous foaming injection molding machine; uniformly mixing same with a supercritical fluid foaming agent in the injection molding machine; injecting same into a mold cavity; and subjecting the resultant to post-treatment so as to obtain a polylactide foam material. The polylactide foam material has a sandwich structure, in which two outer surface layers are solid layers that do not contain any foam, and the sandwiched layer is a foam layer having a cellular structure.

A mixture contains at least one polyether block amide (PEBA) and at least one poly(meth)acrylate, selected from poly(meth)acrylimides, poly-alkyl(meth)acrylates, and mixtures thereof. The mass ratio of PEBA to poly(meth)acrylate is 95:5 to 60:40. The polyalkyl(meth)acrylate contains 80% by weight to 99% by weight of methyl methacrylate (MMA) units and 1% by weight to 20% by weight of C1-C10-alkyl acrylate units, based on the total weight of polyalkyl(meth)acrylate. The mixture can be processed to give foamed mouldings. The mouldings can he used in footwear soles, stud material, insulation or insulating material, damping components, lightweight components, or in a sandwich structure.
