Qnity Brings Semiconductor Expertise to Industrial Valves with Kalrez® Sealing Solutions

Advancing valve reliability and reducing emissions in demanding applications

SHANGHAI, June 16, 2026 - Qnity Electronics, Inc. ("Qnity") (NYSE: Q), a premier technology solutions leader across the semiconductor value chain, is bringing its deep expertise in high-performance materials to industrial valve applications with its advanced Kalrez® sealing solutions. Leveraging decades of innovation in semiconductor manufacturing environments and industrial applications, Qnity enables reliable sealing in demanding valve applications across semiconductor, chemical, energy, and other industrial sectors.

"Qnity continues to advance sealing technologies that address real-world challenges for the most demanding applications," said Brian Ammons, VP and General Manager of Kalrez® Sealing Solutions at Qnity. "With high-performance Kalrez® parts, we help customers reduce fugitive emissions, extend seal life, and improve overall system reliability - enabling safer operations, longer maintenance intervals, and greater efficiency."

Kalrez® perfluoroelastomer materials have a long history in demanding industrial applications and are widely used in semiconductor manufacturing - extreme environments where stringent process conditions require ultra-high reliability. This level of performance is increasingly critical for reducing emissions and improving efficiency in industrial valve systems, where sealing solutions face extreme temperatures, pressures, and chemical exposures.

Featured Kalrez® solutions for valves include:

• Kalrez® KVSP™ valve stem packing: A system designed to minimize valve stem leakage and support fugitive emissions reduction in critical valve services, with reliable performance under high temperature, pressure cycling, and aggressive chemical exposure.

• Kalrez® Spectrum™ 6375 parts: A versatile perfluoroelastomer compound offering broad chemical resistance and strong thermal stability, widely used across semiconductor manufacturing, chemical processing, and oil and gas valve applications.

• Kalrez® 7375 parts: Advanced parts that provide enhanced resistance to hot water and steam, supporting durability and seal performance in valve applications exposed to high thermal stress.

• Kalrez® OG193 parts: Parts engineered for oil and gas valve applications requiring strong resistance to rapid gas decompression, enabling reliable sealing in high-pressure hydrocarbon environments.

Qnity will showcase these solutions at Valve World Asia in Shanghai, June 22-23, at booth F23, where visitors can explore Kalrez® product capabilities and engage with technical experts. As part of the event program, Huang Hui, Technical Service and Development Engineer, will deliver a technical presentation in the Semiconductors and the Pharmaceutical Industry session. Hui's presentation will highlight valve applications across industrial and semiconductor segments, covering key considerations for demanding operating environments, including leakage control, material compatibility, and long-term reliability.
