    SEALING PRODUCTS ARE WIDELY USED
    The sealing industry can be said to be the smallest industry, but sealing products can be used in large industries, which cannot be underestimated. Regardless of aviation, navigation, petroleum, chemical industry, or machinery, power generation, metallurgy, mining, etc., seals are inseparable. In short, wherever there are machines, pumps, pipes, and valves, they all rely on seals. Therefore, although the industry is small, but it involves a wide range of areas.

    Basic Requirements for Sealing Materials

    This paper summarizes the key performance characteristics of compression and lip seals. Stable sealing relies on good medium compatibility to suppress material swelling. High temperatures reduce tensile strength, inducing stress relaxation, permanent deformation and seal failure. For dynamic seals, greater hardness enhances wear resistance and service life. Sealing materials should possess low permanent deformation and high elasticity and resilience, as extreme temperatures aggravateate deformation. Material elasticity provides resilient sealing force for compression seals and compensates eccentric contact stress for lip seals. Proper hardness matches surface roughness and working pressure to avoid leakage and extrusion, despite hardness degradation at higher temperatures. A wide temperature tolerance prevents thermal aging, hardening and elastic performance deterioration.

    Seal Theory

    Seals are divided into compression seals and lip seals based on working principles. Compression seals realize sealing by compressive deformation of the seal in the groove to block leakage paths. Lip seals initially obstruct leakage paths via pre-compressed elastic deformation. When subjected to medium pressure, their sealing lips cling tighter to the mating part for improved sealing performance.
