1 pure white appearance. 2 high and low temperature resistance: Operating Temperature -200 ℃ ~ +250 ℃. (3) Corrosion resistance: resistant to acid, alkali, aqua regia and various organic solvents, and no dissolution, adsorption and precipitation phenomena. 4 pollution prevention: metal elements blank value is low. 5 Insulation resistance: not affected by the environment and frequency dielectric loss, high breakdown voltage. 6. Resistance to atmospheric aging, resistance to radiation and low permeability. 7 self-lubricating: a plastic smallest friction coefficient. 8 non-stick surface: a minimum surface energy of a solid material. 9 softer mechanical properties, with very low surface energy. 10 non-toxic: a physiologically inert widely used in important sectors of the defense industry, nuclear, oil, radio, electrical machinery, chemical industry, etc.
