GORE Filters for High-Purity Chemical ProcessingA family of highly efficient cartridge filters from W. L. Gore & Associates, Inc. (Gore) can dramatically improve product quality, increase production capacity and reduce the total cost of filtration for high-purity bulk chemicals used in semiconductor fabrication and other microelectronics manufacturing processes.

The substitution of GORE Filters can enable improved particle retention, higher flow rates, faster processing times and the use of fewer filters in the microfiltration of high viscosity fluids, acids, bases, solvents and specialty chemicals.

GORE Filters have proven to be an effective and economical solution to challenges such as meeting tighter particle count specifications on existing equipment, reducing processing times and increasing capacity.
For example, a US manufacturer of semiconductor-grade solvent stripper used GORE Filters to reduce processing time by 90% and process 3X the number of batches. The manufacturer realized significantly lower total cost of filtration, and increased throughput without increased capital or labor expense.

GORE Filters were used by a manufacturer of bulk high purity chemicals to eliminate a six-hour recirculation step in a single pass at a reduced particle count without any capital expenditure. The result was a 200% increase in capacity, an increase in product quality, and an increased packaging rate.

An Asian manufacturer of semiconductor-grade chemicals used GORE Filters to achieve an order-of-magnitude reduction in particle counts, with faster filling times and longer filter life. They realized a significant improvement in product quality, increased capacity, and a lower total cost of filtration.

GORE Filters incorporate Gore’s proprietary high-flow ePTFE (expanded polytetrafluoroethylene) filtration media. Gore technology has been used for decades in the world’s best-performing filters for semiconductor, electronics, high-purity chemical and pharmaceutical applications.
