I.
It is made of common asbestos PTFE packing after treatment by special lubricant. It is mainly use for reciprocating pump and high linear velocity （within10 M/S）, it can be applied in stainless steel or chromized rotor without corrosion to the rotor. And it is suitable for alkali, rare inorganic acid, water, water vapor, organic acid, oil, alcohol and other liquid. It can be applied in: paper mill, dyeing plant, food plant, pharmaceutical factory, brewery and so on.
