Polyimide Plastics Vespel®Meldin® Rods Plates Tubes

Polyimide PI in 260 ℃ below the coefficient of elasticity change is small; up to 250 ℃ glass transition temperature, 240 ℃ long-term continuous work; in a wider range of temperatures, with excellent dimensional stability and creep characteristics; flame retardant, low thermal expansion; high mechanical strength, high hardness; creep resistance is superior, high temperature still maintains a good abrasion resistance, lubrication performance is outstanding; corrosion resistance is excellent, resistant to strong acids and most organic solvents, can be resistant to high energy radiation and plasma resistance; the corrosion resistance is excellent, resistant to strong acids and most organic solvents, can be resistant to high energy radiation and plasma resistance; the corrosion resistance is good. Most organic solvents, high-energy radiation and plasma resistance;

Characteristics: ① mechanical properties, good fatigue resistance, good self-lubricating, wear resistance, coefficient of friction is small and is not affected by moisture, temperature, high impact strength, but sensitive to the gap; ② has better heat resistance than PEEK and wear resistance. ③ at high temperatures in the PI exhaust to be less than other materials advanced engineering plastics, can be used for clean requirements of high occasions, in addition to PI contains fewer impurities such as alkali metals, can be used in the semiconductor industry.
