In the past 20 years, the polymer materials used in this area include polyvinyl chloride, natural rubber, polyethylene, polyamide, polypropylene, polystyrene, silicone rubber, polyester, polytetrafluoroethylene, polymethyl methacrylate and Polyurethane etc. The medical plastics industry has attracted much attention for its high added value, high growth rate and broad market potential. By using new plastic materials, medical devices can be made safer and more environmentally friendly. At present, most medical plastics use medical grade polyvinyl chloride (PVC) as the raw material. PVC has been used as a medical material for many years. It is resistant to chemical corrosion and has strong resistance to oxidants, reducing agents and strong acids. Moreover, it is wear-resistant, easy to produce, safe to use and low in cost. This type of material has good compatibility with intravenous fluids and blood, so it is widely used, such as various medical hoses, blood storage devices, dialysis accessories, surgical gloves, medical conditions, and artificial organs. As a medical material, PVC not only needs to meet the material science requirements, but also the following biological requirements: the plasticizers, stabilizers and other additives used are non-toxic, and are not easy to seep out of the PVC material; good biocompatibility, It is not teratogenic or carcinogenic, and does not cause allergic reactions; good blood compatibility, low hemolysis, and good anticoagulation.

It is usually made by adding one or several specific antibacterial agents to the plastic. Because the material itself is endowed with antibacterial properties, various products made of antibacterial plastics have hygienic and self-cleaning functions, and the long-term performance of antibacterial plastics can be synchronized with the service life of the products, which is convenient and economical. The existing PVC plastics are antibacterial. Poor performance.
