We all know that PPS filter bag is resistant to high temperature. How about its temperature resistance
We all know that PPS filter bag is resistant to high temperature, so how about its temperature resistance? 1. Mechanical properties: basically the same as polyester in strength, elongation and elasticity. 2. Flame retardant: PPS filter bag has flame retardancy and spontaneous combustion (LOI oxygen index is 34-35). 3. Radiation resistance: compared with traditional nylon and polyester, PPS filter bag improves the resistance to radiation such as rays and neutral rays. 4. Electrical characteristics: PPS filter bag shows continuous and stable electrical characteristics under high temperature, high humidity and high frequency. 5. It has hydrolytic resistance at 160C or even 500% relative humidity, and the PPS filter bag can even be used for 500 hours at 79% relative humidity. 6. Convenient cleaning can be achieved by processing the lampblack calendar. 7. Heat resistance: PPS filter bag has a high melting point of 85. PPS filter bag has long-term heat resistance, can be used continuously under 190, and has strong steam resistance; It can maintain 90% strength even under 160 high-pressure steam 8. Chemical resistance: chemical resistance can be compared with fluorine fiber. PPS filter bag can be used for most acids with temperature lower than *00c (except for some acids, such as concentrated nitric acid). In addition to several oxidants, alkali and organic solvents also maintain stable chemical resistance.
