The medical field

Breathable but not Bacterion-permeable: The micro - porous structure of TPU membranes allows for oxygen and moisture exchange while blocking bacteria and promoting wound healing.

Low Allergenicity: Medical - grade TPU film has passed the ISO 10993 biocompatibility test, making it suitable for sensitive skin.

Transparent and Visible: It allows medical staff to observe the wound condition, reducing the frequency of dressing changes.

Typical Products: Transparent surgical wound patches, burn repair dressings, diabetic foot ulcer care films.

Flexible and Anti-kinking: TPU film - made catheters resist deformation when bent inside the body, ensuring the smooth flow of liquid medicine or gas.

Chemical and Biological Resistant Liquids: They are anticoagulant and resistant to disinfection methods like ethylene oxide and gamma - ray sterilization.

Enhanced X-ray Imaging: Can be combined with contrast agents such as barium sulfate for intraoperative positioning.

Application Cases: Central venous catheters (CVC), urinary catheters, ventilator tubing, balloon catheters for minimally invasive surgery.

Controllable Permeability: By adjusting the thickness and porosity of the TPU film, precise sustained drug release can be achieved.

Long-term Stability: Avoids the sudden release effect of traditional carrier materials.

Innovation Directions: Transdermal drug delivery patches (such as nicotine smoking cessation patches), implantable chemotherapy drug carriers.

Bioabsorbable TPU Film: After completing its support/repair function (usually 6 - 24 months), it gradually degrades, eliminating the need for secondary surgical removal.

Mechanical Properties Match Human Tissues: More elastic than PLA/PGA materials, suitable for dynamic environments (such as cardiovascular patches).

Cutting-edge Applications: Cardiac occluder membrane layer, orthopedic soft tissue repair membrane, absorbable suture coating.

High Sealing Performance: TPU waterproof membrane at the seams of protective clothing blocks virus/liquid penetration (complying with EN 14126 standard).

Comfortable and Breathable: Compared to traditional PVC, TPU film - made medical gloves fit better and reduce sweat accumulation.

Epidemic-related Products: Adhesive films for key parts of medical protective suits, upgraded sterile packaging bags.

Intelligent Sensing TPU Film: Conductive TPU film with flexible sensors can monitor body temperature and pressure in real time.

3D Printing Compatibility: Acts as a bio - ink carrier for printing personalized tissue engineering scaffolds.

Future Trends: Smart band - aids (with pH value/infection alerts), bionic artificial skin.

Medical Equipment Cable Sheath: Excellent chemical corrosion resistance, wear resistance, and anti - microbial properties, and can withstand various sterilization methods.

Implantable Medical Devices: Such as artificial heart pump components and nerve stimulator packaging, ensuring long-term stable equipment operation.

Orthodontic Invisible Braces: Replacing traditional PETG materials, they are less prone to breaking when put on and taken off and have a good stress retention rate.

Artificial Blood Vessels: High melting strength and good biocompatibility make them ideal for artificial blood vessels.

Chip Coating: Used to address the biocompatibility issue of chips, applied in implantable blood glucose meters and artificial retinas.
