    ### **2. Core advantages of products**
    Hengyao sealing products are known for **excellent engineering materials** and **precision manufacturing processes**, and have the following outstanding properties:
    ✔ **Strong wear resistance**-suitable for high-load, high-frequency motion conditions, greatly extending the life of the equipment.
    ✔ **Extreme temperature resistance**-applicable temperature range **-196℃ to 260℃**, meeting the needs of ultra-low temperature (such as liquid nitrogen environment) and high temperature conditions.
    ✔ **Corrosion resistance**——Can resist corrosion from chemical media such as acid, alkali, oil, solvent, etc.
    ✔ **No creep, self-lubricating**——PTFE composite materials reduce friction, avoid "stick-slip" phenomenon, and ensure smooth operation.
    ✔ **High-precision sealing**——Effectively prevent leakage and improve equipment energy efficiency.
