Extra soft, form-stable and breathable

Bayer MaterialScience AG : 13 October, 2004  (Company News)
Under its textile or leather covering, upholstered furniture almost always features padded quilting that makes up about 10 to 15 percent of its volume. Bayer MaterialScience AG has recently developed an extremely light polyurethane foam for this quilting.
Thanks to the spatial crosslinking of its pores, this highly elastic material, known as HyperNova, is more dimensionally stable than the polyester fiber fleece and other materials traditionally used for this purpose. Anyone purchasing a couch or sofa upholstered with this material can be sure that the padding will retain its resilience over many years. The seat surface remains largely unaffected by frequent use and always recovers its shape when you stand up, leaving no wrinkles or creases.

An additional benefit of this very soft polyurethane foam is its exceptional breathability: it is extremely permeable to air and can absorb up to ten percent of its weight in moisture and emit it again later.

'Thanks to its low density and the associated low raw material costs, HyperNova can easily compete in terms of price with the upholstery materials used up to now and, what's more, it also offers the exceptional properties of polyurethane foam,' says Dr. Sven Meyer-Ahrens, head of development in the Comfort segment of the Polyurethanes Business Unit at Bayer MaterialScience. The breathable foam was manufactured using processes born out of the close cooperation between Bayer MaterialScience and Hennecke GmbH of Sankt Augustin, Germany. The only blowing agent used is carbon dioxide. Environmentally harmful chlorofluorocarbons (CFCs) play no part in the production process.

HyperNova is also impressive thanks to its excellent tensile strength and elasticity. As its surface is hydrophilic i.e. it can absorb moisture uncomfortable electrostatic charges occur less often than with other materials. And there's good news for allergy sufferers too the new polyurethane foam is resistant to mite and microbe infestations.
