1038175 WHAT HAPPENS TO YOUR MATTRESS WHEN YOU'VE FINISHED WITH IT?

The chances are that, even in today's increasingly waste-conscious times, a used mattress will end up in a landfill site. There its bulk and density may well lead to the mattress floating to the top again and again, despite being buried daily under the next influx of rubbish. In the US and Canada, a ... (English)


1038176 DEVELOPING RENUVA-BASED POLYOLS FOR MOULDED FOAM

A Dow Chemical presentation at the 2007 conference of the Center for the Polyurethanes Industry discussed use of natural oil polyols (NOPs) made using Renuva technology in moulded foam applications. This first generation of NOPs was not designed specifically for flexible moulded uses; it was used to ... (English)


1038198 ECO TPU: NEW THERMOPLASTIC POLYURETHANE FROM RENEWABLE SOURCES

A new family of bio thermoplastic polyurethanes is presented, providing TPU grades for injection moulding, extrusion and adhesives. A full range of bio TPU from plant-based sources derived from bifunctional polyols has been developed. The reaction of these polyols in the TPU formulation results in n ... (English)


1038271 FAURECIA BACKS TPU DESIGN AS SHOO-IN FOR NEXT-GEN SEATING

French auto supplier Faurecia thinks that the next generation of automotive seating could eliminate PU foam. With its concept “Sustainable Comfort Seat”, the company replaces foam inside the seat with two sheets of injection moulded thermoplastic PU. The twin-sheet structure is part of a seat system ... (English)


1038318 CARBON NANOFIBRES CUT UPHOLSTERY FLAMMABILITY

Researchers at NIST have found that the addition of a small quantity of carbon nanofibres to the PU foams used in some upholstered furniture can reduce flammability by about 35% when compared to foam treated with conventional fire retardant chemicals. The carbon nanofibres help prevent the foam from ... (English)


1038327 EUROPEAN SHOW FOR PUS

Utech Europe takes place for the second time in MECC Maastricht, the Netherlands, from 31 March to 2 April. This article provides a preview of the show. Under its BaySystems PU system operation, Bayer MaterialScience will showcase lightweight components and technologies for the automotive and refrig ... (English)


1038769 LOW-EMISSION PU OFFERS ADDITIONAL PROCESSING BENEFITS (SHORT ITEM)

It is reported here that Dow Automotive in Germany has introduced a new low-emissions PU which provides better air quality in automotive passenger compartments, as well as offering several further key advantages to car manufacturers. This short article presents brief information about the new PU, wh ... (English)


1038800 STUDY ON FAILURE MODE OF ALUMINUM/PU FOAM SANDWICH PLATE UNDER BENDING LOADS

The competing collapse mechanisms for a simply-supported sandwich beam with LY12 (hard aluminium alloy) faces and a PU foam core subjected to three point bending were studied. Simple analytical models were modified based on published papers in order to predict the collapse load of the sandwich beams ... (English)


1038845 NEGATIVE TEMPERATURE COEFFICIENT OF RESISTIVITY IN LIGHTWEIGHT CONDUCTIVE CARBON NANOTUBE/POLYMER COMPOSITES

The difficulty of preparing a foam conductive polymer composite(CPC) material is shown to be the result of the porous structure making it hard to form a conductive network. Acetone-assisted dispersion was used to disperse carbon nanotubes(CNTs) into PU foam and a lightweight conductive CNT/assembled ... (English)
