From April 12 to April 15, BASF will present new products and customer-orientated applications at INDEX 2011, the world's leading nonwovens exhibition, in Geneva.
At the BASF booth 1426, BASF experts are going to inform and advise business professionals about BASF's comprehensive service and product range in the field of fiber bonding, additives and superabsorbents. BASF is again addressing customers from the hygiene and nonwoven industry and all companies that require environmentally friendly binding agents and liquid-absorbing polymers for their products.
Dispersions for fiber bonding – innovations for nonwovens
Binding agents for fibrous materials in the form of dispersions and reactive resins have become part of our daily life. They hold together a large number of products that simplify our everyday life in many ways. When used in nonwovens, they make roofing membranes tear-proof and ensure that PVC floors keep their shape. Thanks to such dispersions, waterproof cellulose substrates can be turned into highly efficient decorative paper, filters or nonwoven wallpaper. Natural fibers are used to produce light-weight construction material or floor coverings.
At this year's INDEX, one focus in the field of dispersions for fiber bonding will be on the ecologically compatible reactive resins of the Acrodur brand. As a water-based, formaldehyde-free system, Acrodur offers an environmentally friendly alternative to solvent-based or formaldehyde-containing resins and consequently guarantees safe and simple handling.
It is, for example, used as a bonding agent for nonwovens made of polyester and glass fibers in construction applications such as PVC floors and insulating mats. Additionally, Acrodur is particularly suited to process natural fibers. As these fibers are both light and stable at the same time, automobile manufacturers use molded parts made from natural fiber, among other applications, for door linings, shelves or car ceilings. In this way, Acrodur promotes the use of renewable raw materials in the automotive industry and contributes to the production of energy-efficient cars by reducing their weight.
Another focus is on Acronal-branded acrylate dispersions. Apart from conventional applications for polyester and glass nonwoven fabrics, the bonding agents are also suitable for cellulosic substrates. In this field, BASF will, this year, present its innovative formaldehyde-free self-crosslinking Acronal DS 2416 - thanks to this new binding agent, it is easy to process cellulose fibers.
It is, for example, perfectly suited to produce cellulose-based air filters for cars, which need to be particularly durable and powerful. In addition, Acronal DS 2416 has low VOC values, which is important for residential applications. This means that nonwoven wallpapers produced on the basis of Acronal DS 2416 are not only particularly stable but also low-emission.
