3. the sealing ring of rubber material has good elasticity, and the modified composite material has higher operation speed than the ordinary sealing ring;
4.Good rubber follow, good low pressure sealing performance, can be used for pneumatic rotary sealing, high requirements for lubrication conditions, can not be used for pneumatic rotary sealing without lubrication;
5.The pure rubber material is soft and does not withstand high pressure. it is necessary to add clip-woven fiber to increase its hardness and strength.
