Abstract:
The present invention relates to a reinforced composite material, comprising an organic polymer, a silicon polymer, and an interphase between said organic polymer and said silicon polymer, wherein said interphase comprises chemical bonds between the organic polymer and the silicon polymer, and to a method to obtain said reinforced composite material. The present disclosure can be used to improve the mechanical properties of silica aerogels by functionalization of textile materials.
Abstract:
A tufted carpet (10) comprises consecutively a primary backing (12) stitched with loops of yarn (14) to form a tufted structure projecting outwardly from the primary backing (12), a layer of latex (16), a latex of polyolefin (18), and a secondary backing (20) comprising a woven polyolefin.
Abstract:
Die Erfindung betrifft Verbundelemente, enthaltend einen Polyurethanschaumstoff (i), einen Vliesstoff aus thermoplastischem Polyurethan (ii) und gegebenenfalls eine Deckschicht (iii), sowie ein Verfahren zu deren Herstellung und die Verwendung der erfindungsgemäßen Verbundelemente als Sitze oder Teppiche.
Abstract:
A tufted carpet or mat product comprises a primary support fabric having an underside and an upper side, a layer of rubber or synthetic rubber adhered e.g. by vulcanization to the underside of the primary support fabric, and yarn nops extending through the primary support fabric for forming of a nap on the upper side of the primary support fabric and for forming of nap nop bottom parts between the rubber layer and the primary support fabric. In said tufted product the nap comprises 70-95, preferably 80 weight per cent animal wool and 5-30, preferably 20 weight per cent synthetic fibers, such as fibers of acryl, fluorocarbons, polyacetales, polyamides, polyesters, polyethylenes, polypropylenes, polyurethanes and similar fibers being relatively fire inhibiting, the primary support fabric material consists of fibers which per se has a high ignition point, and the rubber layer has been selected from the group of washable rubbers not being fire supporting and which preferably also are resistant against oils, gasoline, acids and bases. Thereby a tufted product is achieved which has a hitherto unknown self-extinguishing or fire inhibiting effect and which is washable after use and dirt and water binding during use.
Abstract:
The present invention provides a high-molecular-weight polyether polyol ensuring that when used as a polyurethane raw material, a polyurethane having excellent flexibility and elastic recovery can be obtained; and a method for producing, with high productivity, a polyether polyol having a higher number average molecular weight and a narrower molecular weight distribution than those of the raw material polyether polyol. The polyether polyol of the present invention has a number average molecular weight of 3,500 to 5,500 and a molecular weight distribution of 1.7 to 3.0.
Abstract:
The invention relates to a multi-layer façade film, comprising a nonwoven fabric layer made of a nonwoven fabric and a film layer made of a plastic film, wherein the nonwoven fabric layer and the film layer are connected to one another. According to the invention: the nonwoven fabric is arranged between two film layers as a middle layer, is made of a thermoplastic elastomer, is elastically extendible in one direction, and is designed as a melt-blown product; each film layer is also elastically extendible in one direction, contains an elastically deformable thermoplastic urethane designated as TPU, and is connected to the nonwoven fabric as an extrusion coating; and the façade film has a yield strength of at least 40% in the longitudinal direction and in the transverse direction, a tensile strength, with respect to a 50 mm wide film strip, of at least 120 N, a maximum s d value of 1.5 m in terms of the vapor permeability of the façade film, and a value corresponding to a water column of at least 8 m in terms of the water impermeability of the façade film.
