According to the actual environment of the customer needs to produce a variety of physical properties and specifications of the wear ring.
Corrosion resistance: the ability to bear in addition to the molten alkali metals, fluoride medium and more than 300 DEG C sodium hydroxide outside all acid (aqua regia), strong oxidizing agent, reducing agent and organic solvent.
Insulation: not affected by the environment and frequency, the volume resistance of up to 1018 ohm cm, dielectric loss of small, high breakdown voltage.
High and low temperature resistance: on the influence of the temperature change is not big, wide temperature range, can use the temperature of -190~260 DEG C. Self lubrication: with the smallest coefficient of friction in the plastic, is an ideal non oil lubricating material. The surface is not sticky: solid materials are known to be unable to adhere to the surface, is a surface can be the smallest solid material.
Atmospheric aging resistance, radiation resistance and low permeability: the long-term exposure to the atmosphere, the surface and the performance remains unchanged.
