Analysis of the advantages of polyurethane elastomer instead of PVC material

The TPU softens when used in the human body. This insert has sufficient rigidity before insertion into the human body, and the flexibility to enter the human body ensures the patient feels comfortable. In addition, the TPU is easy to incinerate and does not release corrosive substances and other hazardous chemicals that can be generated when incinerating PVC. TPU does not require special equipment to process or process, and can be easily disinfected using various methods such as radiation sterilization and ethylene oxide sterilization.

From the point of view of material quality, TPU is significantly stronger than PVC and other alternative materials, and can be made into thin-walled catheters and medical bags with higher internal pressure strength. Medical device structures made with TPU are not only more durable, they use less material, and the resulting medical devices are less likely to be damaged in a frequently used hospital environment. Compared with other materials, it is more resistant to bending, easier to bond, easier to co-extrude with other materials, better biostability and compatibility than other materials. Compared with silicone rubber, it has better mechanical properties and Processing performance, the same strength wall thickness can be thinner, reducing the pain of patients; compared with EVA, with better transparency, and aesthetics. In summary, TPU is the best alternative to PVC in medical devices.

Although PVC is the raw material for traditional manufacturing of medical devices, as people began to pay attention to the environmental impact of PVC and advances in medical research, medical device manufacturers around the world began to use PVC as a raw material to manufacture medical devices. On the contrary, TPU as a substitute for PVC materials, its excellent stability, biocompatibility, processing properties and physical mechanics will certainly develop a broader application in the medical field, gradually replacing PVC as the main raw material for manufacturing medical machinery. This makes the development of TPU more extensive. In short, polyurethane elastomer materials have been increasingly applied to all areas of our daily production and life, and due to its many advantages in performance, polyurethane elastomers have replaced rubber and plastic in many aspects, becoming a new type. The trend of popular polymer materials.
