From chemical industry to semiconductor: Diversified industrial applications of 9900/9900N PTFE gasket materials

9900/9900N modified non-asbestos filled PTFE gasket materials are becoming an indispensable sealing solution in many industrial fields due to their excellent chemical resistance, high temperature resistance and sealing performance. This material not only performs well in the traditional chemical industry, but also shows great application potential in emerging fields such as semiconductors and hydrogen energy.

1. Wide application in the chemical industry
In the chemical industry, 9900/9900N PTFE gasket materials are widely used in the sealing of highly corrosive media such as concentrated sulfuric acid, caustic soda, liquid chlorine, etc. Its excellent chemical inertness and temperature resistance enable it to remain stable in extreme environments, ensuring the safe operation of equipment. For example, in a 98% concentrated sulfuric acid reactor, graphite-filled PTFE gaskets can operate stably for a long time, with a service life of more than 5 years.

2. High-precision application in the semiconductor industry
In semiconductor manufacturing, 9900/9900N PTFE gasket materials are widely used in etching gas pipelines and clean room pipeline interfaces due to their high purity (metal ion content <1ppb) and ultra-clean characteristics. This material is SEMI F57 certified and can meet the strict requirements of the semiconductor industry for sealing materials. In addition, its application in EUV lithography ensures the sealing of the vacuum chamber under extremely low pressure (10⁻¹⁰ Pa·m³/s).

3. Innovative application in the hydrogen energy industry
With the development of hydrogen energy technology, the application of 9900/9900N PTFE gasket materials in high-pressure hydrogen environments has also made breakthroughs. Carbon fiber reinforced PTFE gaskets can achieve a cycle life of more than 5,000 times under a hydrogen pressure of 70MPa, showing excellent durability and sealing performance.

4. Diversified applications in other fields
In addition to chemicals and semiconductors, 9900/9900N PTFE gasket materials are also widely used in food processing, pharmaceuticals, aerospace and other fields. For example, in food processing equipment, its non-toxic and odorless properties ensure food safety; in the pharmaceutical industry, medical-grade PTFE gaskets are USP Class VI certified and can withstand steam sterilization at 121°C.

5. Environmental protection and sustainable development
The non-asbestos filling properties of 9900/9900N PTFE gasket materials make it the first choice for environmentally friendly sealing materials. With increasingly stringent environmental regulations, the application of this material will further promote the green transformation of the industrial field.
