A method for producing carbon or graphite foam parts with high purity level for high-temperature insulation under vacuum or protective gas, as insulating material or as filter material, includes the following steps: introducing dry, foamable starch (1) into an open-top container (2) having a round or angular cross section, until the base (3) of the container (2) is covered amply and uniformly with starch (1); introducing the container (2) partly filled with starch (1) into an oven (4), and heating the container (2) to a foaming temperature of >180? C. over a prolonged period of several hours to foam the starch (1), until the container (2) has filled completely with carbon foam (6); withdrawing the container (2) from the oven (4) and extracting the carbon foam (6) after sufficient cooling, and optionally portioning the carbon foam (6) into carbon foam parts (6.1).

A foaming process for converting fibrous material into a cellular foam structure includes mixing fibrous material and a solvent-based binding agent to form a mixture; saturating the mixture with a pressurized gas to form a gas-saturated mixture; expanding the gas-saturated mixture by reducing the pressure of the pressurized gas to form an expanded mixture with voids in the fibrous material; and curing the expanded mixture to set the fibrous material and drive off the solvent to provide a stable network of fibrous material having cushioning properties.

A thermoplastic starch composition acquired from compounding a mixture comprises starch-containing agricultural waste in 45 to 70% by weight of total composition that the agricultural waste contains starch content less than 50% in dry weight; thermoplastic synthetic polymer in 25 to 50% by weight of total composition; plasticizer in 1 to 10% by weight of total composition; and coupling agent in 1 to 5% by weight of total composition; wherein the compounding is performed at a first temperature which is higher than room temperature.

The present invention relates to the use of a polysaccharide adhesive containing cold water-soluble or cold water-swelling, covalently cross-linked starch as a binder together with a foam generator for producing an adhesive foam.

The invention relates to a method of bonding together surfaces of two or more elements, whereby at least one of the two or more elements is a mineral wool element, said mineral wool element(s) being bound by a mineral wool binder, the method comprising the steps of providing two or more elements; applying an adhesive to one or more of the surfaces to be bonded together before, during or after contacting the surfaces to be bonded together with each other; curing the adhesive, wherein the adhesive comprises at least one protein; at least one phenol and/or quinone containing compound, and/or at least one enzyme.

The present invention relates to a thermosetting binder composition containing water and a water-soluble oligomeric ester of at least one saccharide chosen from reducing sugars, non-reducing sugars and hydrogenated sugars, the hydrogenated sugars being chosen from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol and hydrogenation products of hydrolyzates of starch or of lignocellulose materials, and of at least one polycarboxylic acid, the binder composition having a dry matter content of between 50% and 80% by weight, the water-soluble oligomeric ester representing at least 80% by weight, preferably at least 90% by weight, of the cry matter content of the thermosetting binder composition, and the thermosetting binder composition containing less than 10% by weight, preferably less than 5% by weight, with respect to its dry matter content, of free sorbitol. It also relates to the use of such a binder composition for the manufacture of a product based on mineral or organic fibers which are bonded by an insoluble organic binder.
