Hydrophilic foam from Freudenberg: more effective wound cleansing and optimal patient comfort

Freudenberg Performance Materials will be presenting an innovative hydrophilic foam for wound cleansing for the first time at Compamed in Düsseldorf from November 18 to 21, 2019. The foam enables more effective wound cleansing and increases patient comfort during the cleansing process. Freudenberg will also be showcasing flexible foams for wound dressings with a direct coating of silicone adhesives, which are more effective than conventional foam-silicone constructions.

Active worldwide, Freudenberg Performance Materials specializes in pioneering and manufacturing multi-layer material compositions consisting of hydrophilic PU foams and hydroactive nonwovens. Trade fair visitors will find the company at Booth 8B/H01.

Up to now, wound cleansing (debridement) has been performed using fiber-based products or simply cotton gauze. “Our goal was to develop a more efficient product that cleans wounds more effectively and thus has a positive effect on wound healing. Our continuous, close cooperation with wound experts was decisive in being able to achieve this outstanding development result”, commented Dr. Henk R. Randau, General Manager Business Division Healthcare.

The advantages of the new hydrophilic debridement foam for wound cleansing can be easily summarized:

Ideal for use in wound cavities - Because the foam is soft and flexible throughout, including at the edges, it is ideal for cleansing deep and hard-to-reach wounds.

Better cleansing results and reduced risk - Thanks to its large pores, the foam also easily picks up fibrin coatings and dried exudate. Furthermore, unlike conventional textile constructions, there is no risk of fibers being left behind in the wound.

Less pain, greater patient comfort, - Practical tests have shown that the hydrophilic PU foam achieves a better cleansing result, even when used with reduced pressure.

In collaboration with wound experts and scientists, Freudenberg developed its own test method specifically for this product, which substantiates the performance capability of the new debridement foam. The benchmark for the test was a product that offered the best performance achieved so far in the market (gold standard).

Wound dressings: easier to secure and painless removal

Freudenberg will also be exhibiting foams with a direct coating of silicone adhesives at Compamed. The adhesive properties of silicone make it easier to fix the foam bandage and at the same time allow painless removal achieve a wound de-adhesive effect. Wound dressings with a direct coating of silicone adhesives from Freudenberg are significantly more effective than those with conventional coatings. They are much more flexible, adapt better to the wound bed and enable antibacterial agents to act more effectively. This technology also fulfills Freudenberg’s consistent sustainability strategy. By reducing the number of process steps at the wound dressing manufacturer and thereby reducing production complexity, waste is avoided, energy is saved and the supply chain simplified.

Engineering depth and diversity for composites

Airbond is the latest member of the British Textile Machinery Association (BTMA) to receive recognition for contributions to the composites industry. The engineering firm based in Pontypool, South Wales, has just received the Make UK Energy and Sustainability Award for its Lattice 3D Printing project.

Sustainable, lightweight, and sound absorbing: Polyester-based front trunk solution for BEVs

As car manufacturers look to further reduce their carbon footprint, Autoneum has developed an innovative front trunk solution for battery electric vehicles (BEVs), made entirely from polyester-based textile. The Ultra-Silent Frunk offers significant weight reduction, improved acoustic and thermal insulation, and uses up to 70 percent recycled material, supporting sustainable and efficient vehicle design. Autoneum, global technology leader in acoustic and thermal management for vehicles, has already received orders for the new frunk from three major OEMs in Asia and Europe to be built in three BEV models. Series production for two BEVs has been underway in China and Germany since last year.

Modern testing methods for raw cotton

The 38th International Cotton Conference Bremen will take place from 25 to 27 March 2026 at the Bremen Parliament. This conference has traditionally stood for in-depth expertise and international exchange. The program will focus on technical innovations, market trends, and regulatory frameworks across the entire value chain – from agriculture to the circular economy. With high-profile speakers, the conference is regarded as the key meeting point for the global cotton industry. Today’s focus: Cotton quality and testing methods.

Rieter responds to higher raw material prices

Global political and economic developments have been leading to rising raw material and energy costs for some time. The textile machinery industry is also affected by this trend. Rieter machines and components consist to a large extent of steel, copper, aluminum and electronics. These materials in particular have seen higher demand and higher prices in recent months.
