　　High pressure heating resistance PC SABIC basic HPX4-NA8A005T medical grade

　　Plastic applications in medical plastics have lower costs and can be reused without disinfection, making it suitable as a raw material for the production of disposable medical devices; Processing is simple, and its plasticity can be used to process various useful structures, while metal and glass are difficult to manufacture complex structured products; Durable, elastic, and not as easily broken as glass; Has 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 elastomers, polysulfone, and polyether ether ketone. Blending can improve the properties of plastics, reflecting the performance of different resins, such as polycarbonate/ABS, polypropylene/elastomer, etc.

　　The seven commonly used medical plastics are polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS) and K resin, acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polytetrafluoroethylene (PTFE). After the synthesis of general plastics, they come out of the synthesis tower of large petrochemical plants as flour like powders, which cannot be directly used to produce products. This is what people often say about extracting lipids from tree sap, also known as resin or powder. This is a pure plastic with poor fluidity, low thermal stability, easy aging and decomposition, and is not resistant to environmental aging.

　　In order to improve the above defects, heat stabilizer, anti-aging agent, anti UV agent, plasticizer, etc. are added into the resin powder, and after granulation modification, its fluidity is increased, so as to produce plastic varieties with special properties and different brands suitable for various processing processes. The plastic materials commonly used by medical device manufacturers are modified plastic particles that can be directly used. For products with special properties that are not available in the market, equipment manufacturers can introduce granulation production lines to process and produce plastic pellets through different formula designs. So, there are many grades of the same plastic variety, classified according to the processing method, including injection grade, extrusion grade, and blown film grade; According to performance, there are high rigidity, toughening, and so on. The components in plastic materials cannot precipitate into drugs or the human body, and will not cause toxicity or damage to tissues and organs. They are non-toxic and harmless to the human body. The basic requirements for medical plastics are chemical stability and biological safety due to their contact with medication or the human body.

　　In order to ensure the biological safety of medical plastics, the medical plastics sold in the market are usually certified and tested by medical authorities, and users are clearly informed which grades are medical grade. At present, there is still a considerable amount of medical plastic materials in China that have not undergone strict biosafety certification, but with the gradual improvement of regulations, these situations will be improved. Medical plastics in the United States are usually certified by FDA and USPVI biological testing, while medical grade plastics in China are usually tested by Shandong Medical Device Testing Center. Based on the structure and strength requirements of the instrument products, we select the appropriate plastic type and grade, and determine the material processing technology. These properties include processing performance, mechanical strength, usage cost, assembly method, sterilization ability, etc.
