Sealing Packing Characteristics

① Has a certain degree of elasticity. Under the action of compression force, it can generate a certain radial force and make close contact with the shaft.
② Has sufficient chemical stability. Not polluting the medium, the filling material is not swollen by the medium, the impregnating agent in the filling material is not dissolved by the medium, and the filling material itself does not corrode the sealing surface.
③ Good self-lubricating performance. Wear resistance and low friction coefficient.
④ If there is a slight eccentricity in the shaft, the packing should have sufficient floating elasticity.
⑤ Simple manufacturing and convenient filling.
