Compared with glass and metal materials, the main characteristics of plastics are:

1. The cost is low, it can be reused without disinfection, and it is suitable as a raw material for the production of disposable medical devices;

2. The processing is simple, and it can be processed into various useful structures by using its plasticity, while metal and glass are difficult to manufacture into products with complex structures;

3. Tough and elastic, not as easy to break as glass;

4. Good chemical inertness and biological safety.

These performance advantages make plastics widely used in medical equipment, mainly including polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PC), ABS, Polyurethane, polyamide, thermoplastic elastomer, polysulfone, and polyether ether ketone, etc. Blending can improve the performance of plastics, so that the best performance of different resins can be reflected, such as blending modification of polycarbonate/ABS, polypropylene/elastomer, etc.

The basic requirements for medical plastics are chemical stability and biological safety because they will come into contact with drugs or the human body. The components in the plastic material cannot be precipitated into the liquid medicine or the human body, will not cause toxicity and damage to tissues and organs and are non-toxic and harmless to the human body. In order to ensure the biological safety of medical plastics, the medical plastics that are usually sold on the market have passed the certification and testing of medical authorities, and users are clearly informed which brands are medical grade.

Seven common medical plastics

1. Polyvinyl chloride (PVC, Polyvinyl chloride)

2. Polyethylene (PE, Polyethylene)

3. Polypropylene (PP, polypropylene)

4. Polystyrene (Polystyrene, PS) and K resin

5. ABS, Acrylonitrile Butadiene Styrene copolymers (Acrylonitrile Butadiene Styrene copolymers)

6. Polycarbonate (PC, Polycarbonate)

7. PTFE (Polytetrafluoroethylene)
