1.Microfiltration membrane for semiconductor and microelectronic processing
Purity is crucial in key applications.With optimal retention and flow balance, the ePTFE microfilter media can produce ePTFE membrane filters for semiconductor and microelectronic processing, and provide guarantees of purity and repeatable performance.
The spelt ePTFE microfilter media for pre-filter applications provides a unique combination of highest retention and unmatched flow, ensuring repeatable high performance, consistent quality and superior product cleanliness in key semiconductor and microelectronics manufacturing processes.EPTFE base membranes have pore sizes ranging from 1.0 to 10.0 microns, providing consistency, chemical and heat resistance, and excellent resistance to falling off.
Fluid purity is essential in semiconductor and microelectronics manufacturing processes such as wet etching and cleaning, lithography, and chemical-mechanical flattening (CMP).As transistors shrink, capturing smaller and smaller particles within the nanoscale becomes increasingly important.
2.Characteristics of ePTFE microfiltration membrane
ePTFE membrane consists of millions of interconnected, continuous fibril fibers that reliably trap particles at the nanoscale while allowing high flow rates at a given retention level.
The PTFE composition of our membranes makes them：
Very resistant to shedding
Chemical and heat resistance
It's consistent from a lot to a lot
