10 common medical plastics used in this way

Polymer materials are also called polymer materials. They are mainly composed of polymer compounds as a matrix and other additives (auxiliaries). According to characteristics, it can be divided into rubber, fiber, plastic, polymer adhesive, polymer coating and polymer-based composite materials.

Among them, plastic-based applications are more prominent. Plastics are widely used in various fields because of their excellent properties such as light weight, high strength, temperature resistance, and corrosion resistance, and promote the development of various fields. Plastics are also used in the medical industry. No exception. Especially in the new coronavirus epidemic prevention in recent years, what we have seen the most are medical protective masks, N95 masks, nucleic acid collection tubes and many other epidemic prevention supplies are made of medical plastics. Medical plastics have made huge contributions to epidemic prevention and control.

Currently commonly used medical plastics include engineering plastics and biodegradable materials, as well as some silica gel and other substances. Among them, there are about a dozen types of medical plastics, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyurethane ( PU), PEEK (polyetheretherketone), polytetrafluoroethylene (PTFE), polycarbonate (PC), polystyrene (PS), etc. PVC and PE use the largest amounts, accounting for 28% and 24% respectively; PS accounts for 18%; PP accounts for 16%; other engineering plastics account for 14%. Biodegradable plastics include polylactic acid (PLA), polyhydroxybutyrate (PHB), etc.
