DuPont

Bonded Door Seal products are commonly used in wafer gate valves for various types of semiconductor manufacturing equipment.  DuPont™ Kalrez^® BDS product offers the ability to choose DuPont™ Kalrez^® perfluoroelastomer parts from our product line, combined with a suitable metal material such as aluminum or stainless steel. This allows the creation of the best-fitting BDS for each process application.

This product is manufactured and tailored to meet the needs of each specific application. Along with our renowned DuPont™ Kalrez^® BDS, DuPont proudly introduces our latest product - the detachable type door seal, specially designed to meet your sustainability needs. Developed using our pioneering technology, this product meets the efficient performance and durability.

Additionally, we offer different bonding methods which can be selected based on the specific process requirements. DuPont is introducing a groundbreaking solution to meet the increasing demand for sustainability in the industry. The latest concept door seal, mechanically assembled using Kalrez^® parts instead of being chemically bonding together, is the perfect example of this innovation. While the product looks similar to typical BDS, it features a replaceable Kalrez^® parts seal portion that reduces the need for disposal of the entire assembly when only the rubber portion is damaged.  

DuPont's detachable type door seal offers incredible sustainability advantages beyond being reusable. It provides reductions in BDS disposal, which leads to less clutter and a more environmentally-friendly workspace. Additionally, its innovative design requires less inventory space on-site and results in lower transportation costs.

With this product, DuPont remains committed to helping our valued customers achieve their sustainability goals. Environmental conservation, performance, and durability remain our priorities for user satisfaction.

DuPont's latest technological breakthrough, the DuPont™ Kalrez^® perfluoroelastomer parts low permeation seal, is a game-changer in high-temperature and high-vacuum applications. This innovative product is specially designed to meet the demand for Kalrez^® parts up to 300°C and provides low permeation performance to minimize gas leakage.

These high-performance seals are widely known for their exceptional properties, such as plasma resistance, high-temperature resistance, chemical resistance, and cleanliness.

DuPont's latest innovation, the Kalrez^® parts low permeation seal, was introduced to resolve its higher gas molecular permeation.

This breakthrough seal has significantly improved gas permeation performance in high-vacuum conditions, up to 300°C - the limit for Kalrez^® parts. At DuPont, we're constantly striving to develop innovative solutions that meet the needs of semiconductor manufacturing processes while maintaining our products' superior performance and durability.

Our Kalrez^®  parts low-permeation seal features a unique multi-structure made from Kalrez® parts and metal parts, reducing over 90% of total gas permeation in high-temperature environments. Each seal is individually tailored to the application to fit equipment design and operating conditions for optimal efficiency.

With a focus on customization, users can request Kalrez^® parts and metal part selection for their specific process application. The Kalrez^® parts low permeation seal promises to deliver excellent quality, dependable performance, and efficient operation for high-temperature and high-vacuum applications.

DuPont's technology team developed a special bonding method using original technologies that enable bonding of Kalrez^® parts with functional materials to create composite-structured Kalrez^® parts.

With the growing demand in semiconductor manufacturing, composite structures with other materials are essential for Kalrez^® parts properties. DuPont is committed to delivering innovative solutions and expanding Kalrez^® parts applications to meet our customer's needs.

These innovative parts offer new application opportunities beyond the typical Kalrez^® parts, providing solutions for customer innovation programs beyond traditional applications. DuPont's original bonding technologies used for each raw material used in the manufacture of Kalrez ^® parts are key elements making this possible.  At DuPont, we're committed to delivering cutting-edge solutions to meet the industry's constantly evolving needs. Our team is dedicated to developing and enhancing technologies to provide unparalleled performance and durability of our products.
