Behind our application team in ASNA, our manufacturing facility is dedicated to enhancing ultraclean processing and maximizing manufacturing productivity. Applied Seals Co. Ltd. provides the next generation of advanced sealing components focused on the major ‘clean’ industries we call Semiconductor, Pharmaceutical as well as LED.


    All of our production processes are tightly controlled. Manufacturing and packaging of fluoro-elastomer seals for highly demanding semiconductor applications are performed within Class 10,000 cleanroom environments and Class 100 packaging that includes strict adherence to cleaning procedures for reducing metal contaminants as well as organics.


    This facility delivers the most reliable sealing solutions at the best possible cost of ownership (COO) and with short lead times that have often made the difference in customers whose part requirements were critical. Our products are proven to maintain high-integrity seals while withstanding the thermal variances, harsh chemicals, and ultrafine particles encountered within high-tech manufacturing equipment. Consideration is also given to provide "green" sealing products capable of being recycled.

ASNA product portfolio of materials include those that perform with the highest degree of chemical compatibility, along with those that withstand thermal variances while striving to help our customers understand how sealing integrity includes the complexity of process, hardware and the ever changing demands that our customers require. Whether it involves older generation equipment, or the newest technologies, ASNA is here to serve and become the experts that can be counted on for the best solutions, best service and the trust required to become the supplier of choice for all sealing requirements.
