    At present , the people of the whole country are mobilizing together to fight against the new coronavirus, and we are in a critical period.
    We believe that if we strengthen our confidence and take appropriate measures, we will definitely win the national battle against the new coronavirus

    In this battle, we saw that polymer materials played a very important role

    1.


    Medical masks are mainly made of non-woven fabrics made of polymer materials, taking common medical masks as an example
    .


    In the national standard GB/T 32610, medical masks should be at least 3 layers, which is what we call SMS (2 layers of S layers and 1 layer of M layers).
    Currently, the highest number of layers in China is 5 layers, namely SMMMS (2 layers S-layer and 3-layer M-layer)


    .


    The S in it represents the spunbond layer (Spunbond), and its fiber diameter is relatively thick, about 20 microns (μm).


    .


    At present, these non-woven materials are mainly made of polypropylene, a common polymer material.
    Of course, different layers have different requirements for polypropylene

    In addition, the disposable protective clothing is also made of non-woven fabrics, and the requirements are similar to the non-woven materials of medical masks

    In our understanding, the lens is probably glass
    .
    But in fact, almost all lenses, including spectacle lenses, are made of polymer materials

    .
    The most common ones are PC, PMMA, etc.
    The polymer material lens is light, not fragile, easy to form, high efficiency, and can be made into a special-shaped structure

    Infusion and injection molding supplies

    At present, almost all of the disposable infusion sets and injection needles we use are made of polymer materials
    .
    Infusion tubes, which used to be mainly made of PVC materials, are now a considerable part of TPE materials

    .





    Another large amount is the injection needle, mainly PVC and polypropylene
    .


    Fourth, drug packaging

    Fourth, drug packaging
          There are many kinds of materials for drug packaging.
    Because drugs are solid, liquid, tablet, powder, etc.
    , some use bottles and cans, some use films, and there are also many polymer materials involved, such as PVC, PP, PC, PA,

    etc.

    Materials of medical prefab house
         In order to quickly respond to the development of the epidemic this time, specialized hospitals such as Huoshenshan and Leishenshan will be built within a few days
    .
    According to conventional methods, it is difficult to satisfy with conventional materials

    .
    The two hospitals were built using rapid mobile room technology

    .



    This modular house uses a lot of polymer materials
    .

    In addition, there are various water and sewage systems, communication systems, etc.

    The development of polymer materials has formed great general-purpose materials, great engineering plastics, and special materials used in some special fields for applications in different fields
    .
    It can be said that our current necessities of life are inseparable from polymers

    .
    In this battle against the new coronavirus, polymer materials also play a very important role!
