The invention relates to the use of i) geopolymer and ii) non-brominated, phosphorus- and/or nitrogen-based flame retardants for improving the self-extinguishing properties of a composition comprising polymer. The polymer may be a vinyl aromatic polymer, and may be in a granulate or foam.

Thermoformable and biodegradable cellulose acetate compositions comprising at least one cellulose acetate at least one plasticizer, and at least one additional component chosen from a filler, additive, biodegradable polymer, stabilizer, or odor modifier are disclosed. The compositions are formed into films, sheets, and articles.

The invention relates to a method for producing isocyanurates and isocyanurate-containing polyurethanes, comprising the step of reacting an isocyanate in the presence of a catalyst.

The present invention relates to a molding made of expanded bead foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the expanded bead foam. The two ends of the respective fibers (F) that are not surrounded by the expanded bead foam thus each project from one side of the corresponding molding. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings of the invention from expanded bead foam or the panels of the invention and for the use thereof, for example as rotor blade in wind turbines.

The present disclosure provides an aerogel-containing composition including an aerogel, a water-soluble binder, a foaming agent, and a mixture of water and a polar organic solvent as a solvent, and an insulation blanket prepared using the same. In the aerogel-containing composition, the aerogel is uniformly dispersed in the composition, and when preparing a blanket, an insulation blanket having low thermal conductivity and flexibility of low density is prepared without concern of shrinkage of the substrate for a blanket and detachment of the aerogel during a drying process.

The present disclosure provides an adhesive tape, a backlight module, a display device, and a method for manufacturing a backlight module. The adhesive tape includes: an adhesive body layer; an expandable structure layer on a side of the adhesive body layer and configured to fill a gap between the adhesive tape and a light guide plate of a backlight module through an expansion of the expandable structure layer.

A thermoplastic polyurethane (TPU) foam product with high flatness, and a preparation method and a use thereof are provided. The TPU foam product is prepared by processing aliphatic thermoplastic polyurethane (ATPU) beads with a melting range of 20° C. to 50° C. and a melting point of 90° C. to 160° C. by a physical gas foaming process to obtain foamed ATPU beads and heating the foamed ATPU beads with a heat source to make the foamed ATPU beads fused. The TPU foam product with high flatness has a density of 0.08 g/cm.sup.3 to 0.8 g/cm.sup.3 and a flatness value of less than 2 mm, and the flatness value is determined by a fixed-length ruler. The TPU foam product not only has high flatness such that diversified designs are allowed for a surface of the product, but also has high resilience.

A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.
