Medical grade TPU film preparation

Medical grade TPU film preparation -- Nano film -- YMUS Ultrasonic spraying

TPU is widely used in biomedical field because of its good biocompatibility and mechanical properties. Its use in the medical field has become varied, the main products are artificial heart AIDS, artificial blood vessels, artificial skin and so on. Medical TPU has good flexibility, good wear resistance, high compatibility, no deformation, no allergic reaction, it has good blood compatibility, and shall not affect the blood composition, is widely used in the medical field.

With the progress and development of society, polymer materials represented by PVC and TPU have become the most commonly used biomedical materials. Meanwhile, the application of polymer materials in in vitro diagnostic equipment is becoming more and more important.

Application field:

1. Medical catheter

2. Artificial heart assist device

3. Medical film

4. Medical artificial skin

Traditional PE, PVC film has the advantages of waterproof, anti-liquid seepage. They are popular in medical treatments such as wound dressings and surgical procedures, but they have the defect of not excreting sweat produced by the body's metabolism in a timely manner, causing discomfort such as heat, cold and wet. Therefore, a new medical film is urgently needed to replace such products.

Polyurethane elastomer medical film was prepared by spraying pressure sensitive adhesive on the surface of polyurethane elastomer film. Compared with traditional PE and PVC medical film, TPU medical film has the characteristics of soft, good skin affinity, high elasticity, strong moisture permeability, 100% waterproof and so on, which can effectively prevent the film from falling off during surgery. Inhibit the transfer of various pathogens during the operation. Such as orthopedic surgery, heart valve replacement, intravenous indwelling needle, abdominal and thoracic catheterization, spinal fluid shunt surgery, can significantly reduce the infection rate.

‍YMUS ultrasonic spraying to prepare nano-thin film coating, automatic spraying equipment spraying uniformity up to 95%, precise control of coating thickness, can prepare tens of nanometers to tens of microns of coating. High precision constant current liquid supply technology, can realize 24 hours uninterrupted steady constant liquid supply.‍
