Resin composition and electric insulating sheet
An object of the present invention is to provide a resin composition having excellent heat resistance and excellent thermal adhesiveness, so as to provide an electric insulating sheet having excellent heat resistance. In order to achieve the aforementioned object, the present invention provides a resin composition which contains a polyether sulfone resin and a resin having a specific melt viscosity, and contains at least a phenoxy resin other than the polyether sulfone resin.
Composite material for fluid flow management
A composite material (and its manufacture) is described that has (i) a first layer comprising an absorbent fiber material that is in contact with the area of use on its first side, (ii) a second layer comprising an absorbent material, said second layer being arranged on the second side of said first layer, wherein a plurality of channels extends through the entire first layer, from said first side to said second side thereof, and further extends into at least a portion of said second layer. This composite is of particular use in wound treatment.
NON-FLAMMABLE THERMAL INSULATING COMPOSITE SUBSTRATE FOR MOTOR VEHICLES AND PRODUCTION METHOD
Disclosed is a non-flammable thermal insulating composite substrate for motor vehicles including: a textile component constituted by a layer of needle-sewn non-woven fabric composed of a percentage of pre-oxidized polyacrylonitrile fiber included between 40% and 70%, preferably 58% and of the remaining percentage of polyethylene glycol-terephthalate fiber, the textile component having weight preferably 400 gr/m.sup.2; and a barrier fixed to the textile component using a spreading process, constituted by a thermoplastic resin based on low density polyethylene added with non-halogen flame retardants, the barrier having weight preferably 100 gr/m.sup.2. The composite substrate has the following features: a thickness included between 2 mm and 5 mm, preferably 3.8 mm; a weight included between 300 gr/m.sup.2 and 700 gr/m.sup.2, preferably 500 gr/m.sup.2; odorless; no emission of fumes; dimensionally stable, even at heatstroke, with a maximum variation of 1%; and non-flammability.
Soundproof body and silencer for motor vehicles
A soundproof body is formed by a two-layer lamination structure of a felt layer and a film layer. Some of plural fibers constructing the felt layer are formed to be thicker than the remaining fibers.
MULTI-LAYER SUBSTRATES COMPRISING SANDWICH LAYERS AND POLYETHYLENE
Multi-layer substrates comprising a top surface layer of pulp fibers, a bottom surface layer of pulp fibers, and a melted thermoplastic material layer between the pulp fiber layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F. to 350° F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the pulp fibers top and bottom surface layers that are in contact with the thermoplastic material as it melts.
ADDITIVE FREE FABRICATION OF POLYMERIC COMPOSITES WITH DELAYED AND REDUCED DRIPPING
Multilayer composite materials are described herein. The multilayer composite materials have a first layer comprising a first polymer and a second layer comprising a second polymer. The first layer and the second layer abut each other. The first layer and the second layer each have a thickness in a range of about 10 nm to about 1 mm. The first layer and the second layer are arranged to provide for the multilayer composite material to have reduced dripping and a delayed first dripping time as they undergo a combustion process relative to a single layer material having a same thickness as a thickness of the multilayer composite materials.
Multi-layer substrates comprising sandwich layers and polyethylene
Multi-layer substrates comprising a top surface layer of pulp fibers, a bottom surface layer of pulp fibers, and a melted thermoplastic material layer between the pulp fiber layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F. to 350° F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the pulp fibers top and bottom surface layers that are in contact with the thermoplastic material as it melts.
Films having selectively weakened portions
A non-fibrous film has a non-weakened portion and a weakened portion having at least one mechanical property having a value that is lower than the value of the mechanical property of the non-weakened portion. The film has an optical characteristic including a clarity of at least 75 percent.
Extensible flexible hose, and method and production line for continuously manufacturing thereof
A hose that includes an inner layer and an outer layer made of an elastic polymeric material, and a textile reinforcement layer interposed between the inner and the outer layers. The inner layer and the outer layer are reciprocally coupled to form a unitary tubular member, within which the textile reinforcement layer is embedded. The unitary tubular member has an elasticity such to automatically elongate under the working pressure given by the liquid flowing therethrough to increase its original length and to automatically recover once the working pressure stops. The textile reinforcement layer is adapted to move from a rest configuration when the working pressure stops to a working configuration when the unitary tubular member elongates under the working pressure, and vice versa.
Moulding apparatus for forming a fastening device
