PVC material is one of the world's largest production of plastic products, widely used in the Asian medical device market. However, in recent years, with the improvement of China's comprehensive national strength and people's living standard, China's import of PVC materials gradually reduced, TPE replace PVC materials used in the medical field. Next, we will share with you some comparisons between PVC and TPE.

PVC is a serious harm, TPE becomes a substitute:

PVC material has been eliminated in many other parts of the world because it is considered a medical device manufacturing material with potential safety risks. First of all, during production, vinyl chloride is left behind when PVC resin is synthesized, and processing also breaks down to produce vinyl chloride, which causes cancer, and DEHP plasticizers and MEHP formed after hydrolysis are toxic to the liver and other organs. Secondly, when used, PVC can have an adverse effect on the development of the male reproductive system, and is particularly harmful to infants or pregnant women. After use, it is a question of how to dispose of the PVC material. Because medical devices used for the delivery of medication or blood are regulated, medical devices such as catheters and medical bags must be incinerated after use. However, incinerating PVC releases hydrogen chloride (HCl), which can cause damage to the incinerator. In addition, the combustion process can produce polychlorinated dibenzo-p-dioxins (CDDs), a group of compounds containing 75 substances that produce a wide range of harmful effects, which are released into the air, water, and soil and can enter the human body through these pathways. Numerous studies have shown that dioxins have adverse reproductive, developmental, immunologic and endocrine effects in animals and humans.

One, as opposed to PVC, TPEs do not require plasticizers to gain flexibility, so there is no risk of phthalates migrating from medical devices to pharmaceutical solutions or the human body. Two, medical device structures made with TPEs are not only more durable and use less material, but medical devices made with TPEs are also less likely to be damaged in a frequently used hospital environment. Third, TPE is easy to incinerate and does not release corrosive substances and other hazardous chemicals that are produced when PVC is incinerated.

Therefore, tpe with its excellent bioflexibility, stability, physical mechanics and processing performance has become a safer alternative to PVC in medical device products, and TPE is also in such a market demand, widely used in pharmaceutical packaging, medicine and blood storage and infusion and all kinds of catheters, medical equipment accessories and other medical fields.
