Ultra-high Temperature Resistance
01It has a wider temperature resistance range (from -20°C to 320°C or even higher), and can be stably used in extreme high-temperature processes of semiconductor equipment, such as high-temperature oxidation and sintering. -
Super Strong Chemical Resistance
02It is almost completely resistant to all highly corrosive chemical media in the semiconductor industry, including aqua regia, concentrated sulfuric acid, specialty gases, etc., and is suitable for harsh corrosion environments that fluorosilicone cannot handle. -
Extremely Low Gas Permeability
03In an ultra-high vacuum environment, its outgassing rate is much lower than that of fluorosilicone, and the sealing performance is better, meeting the ultimate requirements for vacuum degree of high-end semiconductor equipment. -
