Enhancing the sealing of O-ring, meeting the customer's requirements for color 
Diversity of O-ring, the cost is much lower than encapsulated of O-ring,
No stickiness (avoid adhesion affecting use and storage)
Improve the temperature resistance of O-ring (low temperature / high temperature)
Reduce friction coefficient
Increased wear resistance
Improve corrosion resistance
Enhance insulation
