1. High self-lubrication, no water absorption-----Destroy molecular chains formed due to water absorption; eliminate sticking; material-feeding is smooth and natural.
      2. Low operation cost: One investment makes you free from worrying about maintenance.
      3. High wear-resistance and impact-resistance---- Multiple kinds of modifiers are added to preserve original characteristics and improve applicability.
      4. Long service life----Get the service life 3 times longer than that of former super high polymers.
