Application of medical plastic products in the medical field

Medical plastic products are widely used in the medical field. From a small syringe to a large-scale medical testing equipment, plastic figures can be seen. First of all, we have to figure out that the medical plastics mentioned here do not refer to those that reach medical grade hygiene level, but refer to all plastic products used in the medical field. Is a large range. First of all, compared with metal materials and inorganic non-metallic materials, plastic products have many advantages that other materials do not have: low cost, they can be used without disinfection and reuse, and are suitable as raw materials for the production of disposable medical devices; Processing is simple, and its plasticity can be used to process a variety of useful structures, and metal and glass are difficult to manufacture into products with complex structures;? Tough, flexible, not as fragile as glass;? Has good chemical inertness and Biosecurity. Currently widely used medical plastics mainly include: Polyvinyl chloride (PVC). According to market estimates, about 25% of medical plastic products are PVC. This is mainly due to the low cost, wide application range and easy processing of the resin. PVC products for medical applications include: hemodialysis tubing, breathing mask, oxygen suction tube, etc. Polyethylene (PE) has high impact strength, low friction, stress crack resistance and good energy absorption characteristics, making it an ideal material for artificial hip, knee and shoulder connectors. Polypropylene (PP) medical PP has high transparency, good barrier properties and radiation resistance, making it widely used in medical equipment and packaging industries. Non-PVC materials with PP as the main body are currently widely used alternatives to PVC materials. The main characteristics of polystyrene (PS) and K resin PS are light weight, transparency, easy dyeing, and good molding performance, so they are widely used in daily plastics, electrical parts, optical instruments, and cultural and educational supplies. ABS, Acrylonitrile Butadiene Styrene copolymers (Acrylonitrile Butadiene Styrene copolymers) ABS has certain rigidity, hardness, impact resistance and chemical resistance, radiation resistance and ethylene oxide disinfection. The application of ABS in medical treatment is mainly used as surgical tools, roller clips, plastic needles, tool boxes, diagnostic devices and hearing aid shells, especially the shells of some large medical equipment.
