| 1022627 | FLAMMABILITY REDUCTION OF FLEXIBLE POLYURETHANE FOAMS VIA CARBON NANOFIBER NETWORK FORMATION | |||||||||||||||
|
The effect of clays and carbon nanofibres dispersed in glycerol propoxylate-block-ethoxylate polyol on the heat release rate and melt dripping of flexible PU foam was investigated using a modified cone calorimeter. The polyol-filler dispersions were characterised by small angle X-ray scattering, laser scattering and optical microscopy and their rheological properties investigated to estimate the rheological behaviour of the melt produced by the thermal degradation of the PU foam. The results obtained revealed that the carbon nanofibres formed an entangled fibre network which eliminated melt dripping and decreased the rate of heat release of the foams. 25 refs.

POLYURETHANE FOAM AND FIRE SAFETY |
|
The fire safety of flexible and rigid PU foams for use in upholstered furniture, mattresses, filled bed products, transport applications, pipe and duct insulation and interior finish and wall cavity insulation is discussed. Tables are included demonstrating the European community classes of reaction to fire performance for linear pipe thermal insulation products and construction products. 54 refs.

SANDWICH PANELS: SUPPORTING GROWTH WITH AN ESTABLISHED TECHNOLOGY |
|
Huntsman is a leading supplier of PU chemicals to sandwich-panel manufacturers across the world. In Europe, Africa and the Middle East (EAME), the market for PU-cored sandwich panels has been growing rapidly over recent years and is currently estimated to be 130 million m^2 a year. The majority of these panels are produced on laminators, while the discontinuous press technique is mainly used for more specialised panel designs. The main advantages of PU-cored sandwich panels, such as lightweight construction, superb thermal insulation and a rapid and economic construction technique, are definitely appealing for an emerging economy such as India. In this article, Huntsman compares use of PU-cored sandwich panels with that of other construction techniques, listing advantages of PU versus other insulating materials. The paper further describes the various foaming technologies currently practised in Europe and their relevance for the Indian market. The situation in Europe regarding PIR/PU preference is discussed, together with the main drivers and future outlook.

PROCESSING OF NANOCLAY FILLED SANDWICH COMPOSITES AND THEIR RESPONSE TO IMPACT LOADING |
|
The fabrication by the co-injection resin transfer moulding process of sandwich panels based on a nanocomposite polyurethane foam containing various proportions of a commercially available nanoclay as core and three-layered plain weave carbon fabric-reinforced epoxy resin composite containing various proportions of nanoclay filler as face sheets is described. The effects of nanoclay content of the foam cores on the impact properties of the sandwich panels were investigated by impact testing with examination of failure patterns by optical microscopy and SEM, and the results are discussed in terms of potential applications. 26 refs.
