Environmental news and technical  innovation in the nonwovens sector

Düsseldorf - Freudenberg Performance Materials will present a range of its latest developments at the upcoming Compamed 2018 exhibition in Düsseldorf, Germany, including the latest MDI-based PU foams and laminates with superabsorbent nonwovens.

The manufacturer of multi-layer material constructions made from hydrophilic PU foams and hydroactive nonwovens will also showcase its latest foams with directly applied silicone adhesives, as well as activated carbon filters for stoma applications.

According to Freudenberg, its foams with a direct coating of silicone adhesives are significantly more efficient than the commonly used foams with a transfer coating. Wound dressings with a direct coating of silicone adhesives are said to be much more flexible, adapt better to the wound bed and enable antibacterial preparations to perform their function more effectively. In addition, the reduction of production process steps and complexity saves energy, avoids waste and simplifies the supply chain.

As a key developer of MDI-based PU foams, Freudenberg says its offers a superior alternative to traditional TDI-based PU foams. When used as components of wound dressings for chronic venous leg ulcers, Freudenberg’s MDI-based PU foams absorb wound fluids much faster, have a far higher retention capacity and significantly increased strength, the company says.

Freudenberg also offers customers laminates made of hydrophilic PU foams and hydroactive nonwovens, which the company produces in series under ISO 13485 conditions. In this process, Freudenberg combines the foam and nonwoven components, which significantly improves the absorption and retention properties of the wound dressings. When specifying the components, customers can choose between MDI- and TDI-based foams.

As an integrated part of ostomy bags, Freudenberg’s high-performance activated carbon filters have been designed to reliably bind unpleasant odours and therefore improve the quality of life for ostomy patients. The company offers numerous variants, both in roll form and as finished products. These meet the special requirements of illostomy or colostomy products, for example. On request, Freudenberg can also manufacture the filters according to individual customer specifications.

Compamed 2018 takes place from November 12-15 in Düsseldorf, Germany.
