Advantages Working--using high temperature-resistant up to a temperature of 250 degrees centigrade. Low temperature resistance--has better mechanical toughness; even if the temperature down to-196 ° c, can keep the elongation of 5%. Corrosion-resistant-to most chemicals and solvents showed inert, acid alkali, organic solvents and water. PTFE tube Best in weather-resistant plastic aging life. High lubrication-is the lowest friction coefficient in solid materials. Do not glue – is the youngest surface tension of solid materials, do not glue any substance. Non-toxic--physiological inertia, as artificial blood vessel and organ implanted for a long time without any side effects. -Electrical insulation-resistance of 1500 volts high voltage electricity.
