Kalrez® is a brand name for a family of perfluoroelastomer (FFKM) products produced by DuPont. Perfluoroelastomers are a type of synthetic rubber with very high resistance to chemicals and heat. Here are some key characteristics of perfluoroelastomers:
-
Chemical Resistance: Kalrez® & CanRez™ are exceptionally resistant to a wide range of chemicals, including acids, bases, solvents, and other aggressive substances. This makes it an ideal material for seals and gaskets in chemical processing environments.
-
High-Temperature Tolerance: Kalrez® & CanRez™ parts can withstand extreme temperatures, often ranging from -40°C to +327°C (-40°F to +620°F), and sometimes even higher for short periods. This high-temperature resistance is far superior to most other elastomers.
-
Durability: Due to robust composition, Kalrez® & CanRez™ materials have excellent longevity and maintain their integrity over long periods, even in harsh conditions. This durability reduces the need for frequent replacements, which can be cost-effective over time.
-
Applications: Kalrez® & CanRez™ materials are widely used in industries where high performance under extreme conditions is essential. These include aerospace, oil and gas, semiconductor manufacturing, pharmaceuticals, and chemical processing. In these industries, Kalrez® & CanRez™ seals and gaskets are used to prevent leaks and protect equipment.
-
Variety: The Kalrez® & CanRez™ product lines includes various grades and formulations designed for specific applications. This allows for customization based on the unique requirements of different industrial processes.
-
Low Outgassing Properties: In vacuum environments, such as those found in semiconductor manufacturing, Kalrez® & CanRez™ materials exhibit low outgassing, making them suitable for ultra-clean processes.
Overall, Kalrez® & CanRez™ materials unique combination of chemical resistance, high-temperature tolerance, and durability make them preferred materials for demanding applications where other elastomers might fail. These specialized properties, however, also contribute to its higher cost compared to standard elastomers. If you are interested in learning more about CanRez™, click here.

Several materials are considered effective alternatives to Kalrez®, a perfluoroelastomer (FFKM) known for its high chemical and heat resistance. Some of these alternatives include:
-
CanRez™: Developed by Canyon Components, CanRez™ is a cost-effective alternative to Kalrez. It is made from nearly identical ingredients and is designed for high-temperature, high-pressure, and chemically resistant applications. CanRez™ offers the same level of performance as Kalrez in various conditions, including high-temperature steam resistance and nearly universal chemical compatibility. It also offers custom geometry options for specific application needs.
-
Simriz®: This is another FFKM compound that offers similar properties to Kalrez. Simriz® compounds such as SZ484, SZ485, SZ486, SZ487, SZ488, and SZ489 are designed for a range of applications, offering resistance to aggressive acids, bases, solvents, and high temperatures. They are suitable for use in environments similar to those where Kalrez® is typically employed.
-
Chemraz®: Chemraz® is another FFKM material with a base resin chemistry similar to Kalrez®. While no two elastomers are fully interchangeable due to variations in fillers and cure agents, Chemraz® is often mentioned as a comparable alternative to Kalrez®, especially in lower temperature applications.
Each of these alternatives offers specific advantages depending on the application requirements, including chemical resistance, temperature stability, and physical properties. It's essential to evaluate each material's suitability based on the specific conditions of the intended application. If you are interested in learning more about CanRez™, click here.

Kalrez®, a product line from DuPont, is a type of perfluoroelastomer (FFKM) known for its exceptional properties and performance. Like CanRez™ FFKM, Kalrez's high cost can be attributed to several factors:
-
Material Composition and Manufacturing Process: Kalrez® & CanRez™ materials are made from perfluoroelastomer, a class of synthetic rubber that provides outstanding resistance to heat and chemicals. The raw materials for FFKM are costly, and the manufacturing process is complex and precise, leading to higher production costs.
-
Performance Capabilities: Kalrez® & CanRez™ are designed for extreme environments and can withstand high temperatures, aggressive chemicals, and harsh conditions where other non-perfluoroelastomer materials would fail. This level of performance justifies a premium price, as it often outperforms other non-perfluoroelastomer seals in demanding applications.
-
Longevity and Durability: While more expensive upfront, Kalrez® & CanRez™ parts often last longer than those made from less expensive materials. This durability can lead to cost savings over time, as there's less need for replacement parts and maintenance.
-
Specialized Applications: Kalrez® & CanRez™ materials are often used in critical applications such as aerospace, chemical processing, semiconductor manufacturing, and pharmaceutical industries. The specific requirements of these industries for high-performance materials add to the value and cost of Kalrez® & CanRez™ materials.
-
Research and Development Costs: The development of specialized materials like Kalrez® & CanRez™ involves significant research and development expenses. These costs are often reflected in the final price of the product.
In summary, the combination of its advanced material properties, manufacturing costs, performance capabilities, and the specific demands of the industries it serves, along with R&D investments, contribute to the high cost of Kalrez® & CanRez™ materials.
