In the medical field, polyurethane elastomer (TPU) is the best substitute material for PVC. Because PVC has the opportunity to release phthalates from medical devices, which can have negative effects on the human body.

TPUs become soft when used in the body, so they are hard enough before insertion and flexible enough after insertion to ensure patient comfort.

In addition, TPUs are easy to incinerate and do not release corrosive substances or other hazardous chemicals that occur when PVC is burned. TPU does not need special equipment processing or treatment, can be easily used for various methods of disinfection, such as ray disinfection, ethylene oxide disinfection.

TPU is occupying the PVC market with its unique advantages. From the perspective of material quality, the strength of TPU is significantly higher than that of PVC and other alternative materials, which can be used to make thin-walled catheters and medical bags with higher internal compressive strength. Medical device structures made with TPUs are not only more durable and use less material, but they are also less likely to break down in a frequent-use hospital environment.

Compared with other materials, compared with TPE, more bending resistance, easy to bond, easier to co-extrude with other materials, biological stability and compatibility is better; Compared with silicone rubber, it has more excellent mechanical properties and processing performance, the same strength can be thinner wall thickness, reduce the pain of patients; Compared with EVA, it has better transparency and aesthetic degree.

To sum up, TPU is the best substitute material for PVC in medical devices.

Although PVC is a traditional raw material for manufacturing medical devices, medical device manufacturers around the world began to abandon PVC as a raw material for manufacturing medical devices as people began to pay attention to the impact of PVC on the environment and the progress of medical research. On the contrary, TPU as a substitute for PVC material, its excellent stability, biological compatibility, processing performance and physical and mechanical properties will be developed in the field of medicine more extensive applications, gradually replace PVC as the main raw material for manufacturing medical machinery.
