How to choose filter cartridges in the semiconductor industry

The material of semiconductor filter cartridges is a crucial factor in semiconductor processes, as they must ensure the highest purity, lowest particle dissolution, and optimal chemical stability. The following are some of the main materials commonly used in manufacturing semiconductor filter cartridges:
Polytetrafluoroethylene (PTFE): PTFE is a high-performance material with excellent chemical stability and extremely low particle dissolution. It has good corrosion resistance to many chemical substances and is suitable for high-purity semiconductor processes.
Polypropylene (PP): Polypropylene is a commonly used filter material with good physical and chemical stability. It is suitable for many industrial applications, especially when high purity and economy are key considerations.
Polyester (PET): Polyester is a synthetic fiber material that is resistant to heat and chemical corrosion, suitable for high temperature and high pressure applications.
Glass fiber: Glass fiber is a high-strength, high-temperature stable material suitable for applications under special high temperature, high pressure, and corrosive conditions.
Stainless steel: Under certain high temperature and high pressure process conditions, the stainless steel support frame or screen can serve as the support structure for the filter element, providing additional mechanical strength and stability.
High purity metals: For applications with extremely high purity requirements, such as certain advanced semiconductor processes, high-purity metal materials may be used, such as 316L stainless steel or other special alloys.
When selecting the material for semiconductor filter cartridges, multiple factors such as process requirements, fluid characteristics, operating conditions, and economy need to be considered. The correct material selection can ensure the best filtration performance, lowest pollution risk, and longest service life, thus supporting the high quality and efficiency of semiconductor manufacturing.
