Product Briefing Outline: W. L. Gore & Associates (Gore) has added hydrophilic PTFE filters to its expanding line of cartridge filters for bulk high-purity chemicals used in microelectronics manufacturing, including LCD, semiconductor, hard-disk drive and photovoltaics.
Problem: Gore filters for high-purity chemical processors can be used as drop-in replacements for existing filters to achieve significant flow improvements while maintaining or increasing particle retention. This increased performance can provide a retention upgrade while maintaining system flow, reducing processing time, or decreasing the number of filters required for a lower total cost of ownership.
Solution: The new filters incorporate Gore's proprietary high-flow hydrophilic PTFE (polytetrafluoroethylene) filtration media, which do not require IPA (isopropyl alcohol) pre-wetting and completely eliminate de-wetting issues in most applications. They are well suited to filtration of aqueous and high-surface-tension liquids, especially where out-gassing or bubbles are a concern. Applications include high-throughput filling, packaging and recirculation systems.
Applications: Bulk high-purity chemical filtration.
Platform: Gore's PTFE filtration media is incorporated into standard-size filters that can be used as drop-in replacements for existing filtration systems and industry standard housings.
Availability: Currently available.
