Qnity to debut Kalrez® innovations
Following DuPont’s intended spin-off of its electronics business targeted for Nov. 1, 2025*, Qnity Electronics, Inc. (“Qnity”) is expected to be one of the largest and broadest publicly traded, global solutions providers for the semiconductor value chain.
Featured products will include:
Kalrez® 9400 parts: a new high-temperature Kalrez® grade designed for reliable performance in harsh process conditions
Kalrez® UPHT: the newest ultra-pure and high-temperature Kalrez® grade for advanced plasma applications
Kalrez® PF3: precision-engineered, pre-assembled, custom flange fittings
These innovations are all designed to meet the purity, precision, and durability needs of next-generation IC manufacturing.
Kalrez® 9400 Parts
Engineered to withstand aggressive plasma environments dense with reactive hydrogen and oxygen species, Kalrez® 9400 parts are designed to deliver a balance of low erosion and minimal particle generation, which are critical for yield and uptime. This product formulation has also demonstrated robust thermal stability, maintaining sealing integrity under prolonged high temperatures, helping support longer preventative maintenance cycles.
Attendees can visit DuPont’s booth to see a variety of displays including a model of the Mars Perseverance Rover and a cell phone teardown station. Experience live product demonstrations and consult with our experts to discover how DuPont can be your trusted partner in advancing innovation and driving technology forward.
Kalrez® UPHT (Ultra-Pure and High Temperature Plasma Grade)
The newest Kalrez® plasma grade, UPHT, is engineered for resistance to high temperature radical-rich plasma conditions at elevated temperatures. In internal comparative testing, Kalrez® UPHT demonstrated minimal particle generation coupled with lower trace metals content and outgassing than previous Kalrez® grades, making it suitable for advanced wafer fabrication processes that demand extremely low defectivity.
Kalrez® PF3 (Kalrez® Custom Parts: Pre-Fit Flange Fittings)
Designed with precision-engineered metal and Kalrez® FFKM components, these custom parts help avoid mismatched sizes and sealing failures due to thermal expansion. They enable reliable, leak-free installations—eliminating field-fit guesswork.
These expansions to the suite of Kalrez® parts reflect Qnity’s continued commitment to enabling semiconductor performance at scale. As new industry needs emerge, Qnity continues to expand its offerings for advanced Kalrez® sealing technologies and invest in the infrastructure needed to support increasing global demand.
Expanded Capacity and Supply Assurance
To meet rising global demand, Qnity has increased its manufacturing capacity for Kalrez® parts by 30% over the past two years. This strategic investment was completed to provide supply reliability for semiconductor and industrial customers. The vertically integrated manufacturing of Kalrez® parts—from polymer synthesis to custom part production—delivers consistent quality, traceability, and end-to-end solutions tailored for critical applications.
“Kalrez® products are more than a sealing solution—they are a performance enabler for the semiconductor industry’s most advanced processes,” said Brian Ammons, Kalrez® Global Business General Manager, Qnity™, DuPont Electronics. “Further, our investments in expanded capacity and innovation reflect our commitment to helping customers achieve reliability, purity, and precision at scale.”
Celebrating 50 Years of Kalrez® Innovation
2025 marks the 50th anniversary of the Kalrez® brand, a pioneer in sealing technology. For five decades, Kalrez® products have delivered exceptional chemical and thermal resistance, enabling breakthroughs in semiconductor manufacturing, chemical processing, aerospace, and other applications. This milestone celebrates a legacy of reliability, innovation, and customer partnership that continues to shape the future of high-performance sealing. Qnity will celebrate the 50th anniversary of the Kalrez® brand through in-booth events at SEMICON West Oct. 7-9 in Phoenix, Ariz. at the Phoenix Convention Center.
