    Ordinary rubber O-ring after polytetrafluoroethylene (PTFE) spraying, the performance of the product will be greatly improved, surface spraying polytetrafluoroethylene this way can make ordinary O-ring products have the following characteristics:

    1. Non-sticky
    After the spraying of ptfe, most of the substances are not able to bond with the O-ring, even if the thickness of the coating is relatively thin, but also to give full play to the non-viscosity of the coating;

    2. Heat resistance
    Because of the ptfe material itself has a good low temperature resistance, high temperature performance, so the temperature of PTFE spraying O-ring is widely applicable, even in the low-temperature state of -240℃, still will not crack, at 288℃ temperature, there will be no melting;

    3. Wear resistance
    After ptfe spraying, the friction coefficient of O-ring is relatively low, although under the load sliding state, its friction coefficient will change, but the range of numerical change is small.  Under high load, the wear resistance of the O-ring after ptfe spraying can still be maintained well;

    4. Moisture resistance
    Ptfe spraying o-ring surface is not easy to touch water, also not easy to touch grease, in the process of use, if stained with stains, will be relatively easier to wipe, so there is no need to stick to the product surface oil, oil processing, waste a lot of production time;

    5. Corrosion resistance
    Polytetrafluoroethylene spraying o-ring has good acid and alkali resistance, in strong acid, strong alkali solution, even in the strong oxidant, the product performance will not be too much affected.

    Ptfe spraying O-ring way although it seems to be only a trivial small process, but it makes a lot of industrial production of sealing needs to be met, I believe that through the above content, you for PTFE spraying surface treatment of O-ring products also have a further understanding!
