TPU film is widely used in various medical devices, including as a coating or outer layer for catheters, drainage tubes, surgical sutures, and other medical supplies, enhancing wear resistance, fold resistance, and anti-slip properties. Its transparency allows medical staff to observe the conditions within the tubes. It is used in the production of gaskets and connectors for respiratory masks and oxygen masks, ensuring a tight seal and comfort. It also acts as a protective layer for sensors, preventing external interference and improving device reliability.
TPU film is a thermoplastic polymer material made of polyols and diisocyanates. Its hardness range is 60HA-85HD. It has high elasticity (elongation at break>400%), wear resistance, and tear resistance. Aliphatic TPU has a better molecular structure and is significantly more resistant to yellowing than aromatic TPU.Temperature resistance covers -40℃ to 120℃, and can maintain stable performance in a wide temperature range.Medical-grade TPU film is FDA-certified and has excellent biocompatibility, and will not irritate human tissue or cause allergic reactions.
TPU film is widely used in the packaging of medicines, medical devices and medical supplies due to its good barrier properties and transparency. It effectively protects products from external environmental influences, keeps them clean and hygienic, and has good heat sealing and printability, facilitating
the automation of the packaging process and clear labeling.
TPU film can also be used in medical protective equipment, such as protective clothing, surgical gowns, gloves, etc., to provide medical staff with an additional layer of protection and reduce the risk of infection.TPU film has become an ideal dressing substrate due to its good air permeability, water resistance and biocompatibility. It is used to make various medical tapes, such as surgical tapes, fixing tapes, etc., to ensure the stability of medical supplies such as dressings and catheters.Medical catheters made of TPU material are light and flexible, can prevent radiation damage, and can replace metal endotracheal tubes
TPU is generally more flexible and elastic than PVC film and is environmentally friendly, while PVC produces harmful substances during production and processing. TPU is also better than PVC in terms of transparency and is suitable for medical applications with high requirements for appearance.
With its excellent comprehensive performance, TPU film has become an indispensable functional material in modern medicine. From traditional medical devices to innovative drug delivery systems, from basic protective equipment to high-end implantable devices, the breadth and depth of TPU film applications continues to expand. With advances in materials science and evolving medical needs, TPU film products with enhanced functionality, improved safety, and improved environmental friendliness will continue to emerge, providing higher-quality material solutions for the healthcare industry. The future application of TPU film in cutting-edge fields such as personalized medicine and intelligent medical devices is particularly exciting.
