Medical-Grade 0.25mm Black TPU Film

This Medical-Grade 0.25mm Black TPU Film is a high-performance polymer film manufactured to stringent medical device standards. With a thickness of 0.25mm, it provides enhanced mechanical strength and puncture resistance compared to thinner gauges, while maintaining excellent flexibility. The black colorant is fully integrated, offering superior opacity for light-sensitive applications and a consistent, professional appearance. The film is engineered for exceptional weldability, forming strong, hermetic seals that are crucial for the integrity of inflatable bladders. Its medical-grade formulation ensures biocompatibility and resistance to common cleaning agents and sterilants (where applicable), supporting its use in both sterile and non-sterile medical environments. It serves as a versatile core material for constructing durable, reliable pneumatic chambers and protective layers in a wide range of therapeutic and surgical devices.

Key Features & Benefits

• Enhanced Durability & Puncture Resistance:​ The 0.25mm thickness provides superior strength and resistance to tears, abrasion, and punctures, ensuring reliability in rigorous medical settings and during repeated use cycles.
• Medical-Grade Safety:​ Manufactured from compliant materials suitable for medical device contact, meeting relevant biocompatibility and regulatory requirements for patient safety.
• Excellent Airtight Seal & Reliability:​ Forms a flawless, monolithic barrier essential for maintaining precise and consistent air pressure in pneumatic systems, such as tourniquet cuffs.
• Superior Weldability & Seal Integrity:​ Specifically formulated for strong, consistent, and leak-proof high-frequency (HF) or thermal welds, creating durable seams for long-lasting bladder performance.
• High Opacity (Black):​ The black coloration provides complete light blockage, which is critical for applications where UV or light sensitivity is a concern, and prevents internal components from being visible, offering a clean aesthetic.
• Chemical & Sterilization Resistance (Compatible):​ Resistant to degradation from many disinfectants, alcohols, and can be compatible with certain sterilization methods (e.g., EtO, Gamma), supporting reprocessing protocols for reusable devices.
• Flexible & Conformable:​ Maintains pliability across a practical temperature range, allowing it to conform to anatomical shapes without restricting function or comfort.
