New material for wound care

Broad range of application from adhesives to backing films


The objective of wound care today is to relieve pain and shorten treatment times as much as possible so that patients can return more quickly to their daily lives. This, in turn, can reduce overall nursing care and the associated costs. Bayer MaterialScience has recognized this trend and developed material solutions based on polyurethanes for wound treatment. At the Index14 trade show from April 8-11 in Geneva, Switzerland, the company is presenting new and marketable developments.

The Baymedix line includes a number of raw materials for wound dressings that promote healing and offer numerous possibilities for the dressing design. The products manufactured from these materials include such things as skin-friendly adhesives, absorbent foams and waterborne polyurethanes for stretchable and resistant backing films.

The Baymedix FD product line for films and medical coverings is one of Bayer MaterialScience's main focal points at the trade show. The backing films protect a wound from contamination and external influences. Using a transfer coating, the films can be applied to foams, non-wovens or textiles. Depending on the requirements, this process creates protective, breathable, foamed soft-touch or compact films.

For more exacting demands, Bayer MaterialScience offers its special Baymedix FP520 crosslinker and support with its formulation. This product stabilizes a film against the disinfectants and other liquids typically used in hospitals.

A combination of the crosslinker with Baymedix FD103 has proven effective in textile covers, paving the way for waterborne, environmentally compatible materials, e.g. for surgical clothing and bedding for people suffering from incontinence.

Many patients ask for wound dressings that contain no latex or other allergens. For them, Bayer MaterialScience has developed the Baymedix CD line of allergen-free, odorless polyurethane dispersions. They support the formulation of simple films that can be applied either as seamless films by dipping or as roll stock film by casting.
