We develop and manufacture polyurethane film from a wide range of resins and additives, allowing us to fine tune the qualities polyurethane/PU film can offer, such as:
We extrude both monolithic and micro-porous polyurethane films, onto a variety of carriers to achieve the best fit for the end-product. The stripping load of the polyurethane film to the carrier can be adjusted from 1-8g/cm, enabling the film to match our customer’s process.
Through the selection of polymers and additives, we can adjust the amount of moisture transfer through our PU films. It is this feature of our films that allows the long wear times of wound care dressings while keeping the covered area dry. Some films, such as PE based films; need to be perforated to achieve this. Our thickness range of breathable films for wound care applications is 0.6 mil to 4 mil.
We have films that can change their moisture absorption depending on the presence of water. So in a dry environment, they will have a low moisture transfer rate and in a wet environment, the film will wick away the moisture at a higher rate.
Our PU films are easily extensible-easy to stretch, elastic, and soft when compared to PE film. This leads to comfort and increased wear-ability, when compared to PE, Fabric or PVC. Because the product conforms to the shape of the area, stretches, and rebounds, bandages or dressings will stay on longer.
The ability to stretch and rebound can mean that if the polyurethane film is used in laminations, the laminated product can retain its flexibility. When used in inflatables or gel pads the stretchiness can produce puncture resistance.
Polyurethane is a naturally strong product and used in many areas as surface protection. Polyurethane also has a high chemical resistance. We can adjust heat resistance to suit needs. We also offer durable puncture resistant PU films for demanding applications such as inflatable products.
There is no need to perforate our breathable film products so the polyurethane film will remain wterproof and a complete barrier to bacteria.
Supported films can give big advantages in processing, allowing easier handling. Some end products incorporate the support carrier in their final presentation. With a stretchy thin polyurethane film, the support carrier will allow printing and adhesive coating. Paper carrier; can help give matt finish to film, it can be die cut. Flexi carriers; give high-quality look and feel, can be conformable (used as part of the application process), can be clear to aid positioning. Unsupported polyurethane film can reduce process waste and are easy to process.
Our advanced knowledge and management of adhesives allow us to provide a variety of adhesive technologies, through downstream partnerships, which are suitable for a wide range of medical applications using PU coating films.
We have a specialty adhesive, specifically developed for smaller consumer or first aid bandages which has ISO 10993 approval. It is a high-grab/instant tack adhesive that can be sterilized and will not give adhesive offset (adhesive left on the skin upon removal). We also offer a skin friendly adhesive for larger professional dressings.
Our adhesives are breathable which allows longer wear without skin maceration, and we are developing a low trauma adhesive that will not distress the skin surface upon removal.
