7 kinds of commonly used medical plastic

     Polyvinyl chloride (pvc)

     Polyethylene (PE)

     Polypropylene (PP)

     Polystyrene (PS) and K resin

     Acrylonitrile-butadiene-styrene (abs)

     Polycarbonate (PC)

     Polytetrafluoroethylene (PTFE)

  Compared with glass or metal materials, Main features of plastic:

     • Low cost, no need for disinfection and reuse, suitable for use as a production material for disposable medical devices;

     • Simple processing, the use of its plastic can be processed into a variety of useful structures, but metal and glass is difficult to create a complex structure of the products;

     Tough, elastic, not as broken as glass;

     • Good chemical inertness and biosafety.

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

  In addition, there are actually two other material in the pharmaceutical industry is very widely used, that is, PET material and HDPE material. In the use of small medical bottles, PET material is widely used, whether it is a medicine pill or liquid medicine, plastic PET bottles have a very obvious advantage in the use of pharmaceutical packaging because of high transparency, light, not easy to break, food safety level and other advantages. While the other material HDPE, is more applied to the packaging of pharmaceutical capsules, it usually has white opaque appearance, and with tamper evident cap, the capacity is generally small, suitable for small granular capsules, convenient to take in batches.

  The plastic bottles of PET materials and HDPE material are more common in China, and their production processes are more skilled in our factory, so if mass production, offers and convenience are more.
