Ürün Açıklaması

XL Medical Grade TPU Film 0.25mm Black

Medical Grade TPU Film for Inflatable Medical Devices

The black matte surface gives the material a consistent appearance while helping reduce visible marks from routine handling. For manufacturers of medical air cells, compression garments, patient positioning systems, and inflatable orthopedic products, the film provides a workable material platform for both prototype development and volume production.

The material is supplied with test compliance for key biological evaluation areas, including cytotoxicity, skin sensitization, and skin irritation according to the ISO 10993 tests specified for this product. These test results are particularly relevant when selecting TPU film for medical devices that may come into direct or prolonged contact with the skin.

0.25mm TPU Film for Controlled Flexibility

Film thickness has a direct effect on the behavior of an inflatable medical component. A film that is too thin may provide excellent flexibility but may not offer sufficient resistance to handling, puncture, or repeated mechanical stress. A thicker film can provide additional material strength but may increase stiffness and affect how an air chamber folds or expands.

The 0.25 mm specification provides a balanced starting point for inflatable medical constructions where flexibility and physical resistance both matter. The 85A Shore A hardness gives the film enough body for converting and welding while retaining the pliability needed for air cells, cuffs, sleeves, and flexible pressure chambers.

For OEM projects, thickness and hardness can be evaluated together with the finished chamber size, operating pressure, folding pattern, welding configuration, and expected inflation cycle. The film specification should therefore be selected according to the complete product structure rather than thickness alone.

Medical Grade TPU Film with ISO 10993 Test Compliance

Material selection for healthcare products requires more than mechanical performance. For components that come into contact with the patient’s skin, manufacturers also need information about biological safety and material composition.

This Medical Grade TPU Film has been evaluated in the following areas:

Cytotoxicity according to ISO 10993-5:2009
Skin Sensitization according to ISO 10993-10:2021/2023
Skin Irritation according to ISO 10993-23:2021

These evaluations provide relevant material information for manufacturers developing medical inflatable products and other skin-contact components. The supplied material specification also identifies the film as plasticizer-free, latex-free, and free from heavy metals.

The TPU formulation is suitable for applications where low odor and resistance to routine exposure to bodily fluids and clinical cleaning chemicals are important material considerations. Final product compliance depends on the complete device construction, manufacturing process, intended use, and applicable regulatory requirements.

Black TPU Film for Medical Air Chambers

Black TPU film can be used where a darker, low-reflective surface is preferred for the finished medical product. The matte finish also provides a more controlled visual appearance than a glossy film, which can be useful for equipment surfaces that are frequently handled or inspected.

For inflatable medical products, the film forms the flexible barrier of the air chamber. The final performance depends on film selection, chamber geometry, welding parameters, seam width, pressure conditions, and the construction method used by the manufacturer.

Typical structures include single-layer film constructions as well as laminated or textile-reinforced designs where additional mechanical support is required.

HF and Ultrasonic Welding for Sealed Medical Components

Medical inflatable products depend heavily on seam quality. The film needs to convert consistently so that welded areas can withstand inflation pressure and repeated deformation during use.

XL TPU Film-Black is suitable for High-Frequency welding and ultrasonic welding. These joining methods can create sealed seams without conventional needle perforations, making them suitable for inflatable structures where air retention is an important part of product performance.

HF welding is particularly relevant to products containing multiple air chambers or shaped bladder sections. Manufacturers can use dedicated welding tooling to define chamber geometry and seam patterns according to the finished component.

Ultrasonic welding can also be considered for specific structures and component configurations. Actual welding parameters should be established through production trials because equipment frequency, power, tooling, welding time, pressure, and film structure can all affect the final joint.

Resistance to Repeated Inflation and Deflation

Medical air chambers may experience repeated pressure changes throughout their service life. Alternating pressure mattresses, compression sleeves, patient positioning bladders, and inflatable splints can all involve recurring inflation and deflation rather than static use.

The elastic nature of TPU allows the film to flex with changes in chamber volume while maintaining a relatively consistent material structure. The 0.25 mm film thickness provides a practical balance between flexibility and resistance to mechanical handling.

For product development, repeated-cycle performance should be assessed on the finished inflatable component. Factors such as chamber dimensions, operating pressure, seam configuration, bending radius, inflation frequency, and contact with external materials can influence the actual service performance.

Resistance to Clinical Fluids and Cleaning Conditions

Medical inflatable components can be exposed to sweat, bodily fluids, cleaning agents, and routine handling during clinical use. Material resistance therefore needs to be considered alongside flexibility and weldability.

The polyether-based TPU construction provides a suitable material base for applications requiring resistance to common handling conditions and exposure to clinical environments. The black surface can also help maintain a consistent appearance when the component is frequently handled.

Cleaning and disinfection procedures should be validated on the finished product using the actual chemicals, concentrations, contact times, and temperatures specified by the manufacturer. Compatibility with a particular disinfectant should not be assumed solely from the film material.
