Packing will affected by sealing medium such as temperature, pressure, PH and the equipment line speed, surface roughness, coaxiality, radial jump and eccentricity etc,. so the packing material should have a features below,

　　1.Temperature resistance.

　　2. Elastic-plastic property.

　　3. Chemical stability.

　　4. Making sample and low price.

　　5. Not permeability.

　　6. Good self-lubrication.

　　7. Easy to install and remove.

　　The above features will affect directly the sealing performance and service life of the packing, and very few materials can fully meet all the above performance, it is very important to obtain high quality sealing material and improve its performance.
