FFKM Kalrez® seals

FFKM Kalrez® seals are a high-performance sealing solution specially designed to withstand extreme conditions. They are made of perfluoroelastomer rubber (FFKM), combining the chemical resistance of fluoropolymers with the high flexibility of elastomers. This combination ensures long-lasting tightness and resistance to temperatures up to +330°C. FFKM seals are indispensable in many industries where reliability and hermetic sealing under tough conditions are required. Their exceptional properties make them suitable for use in the chemical, petrochemical, semiconductor, food, pharmaceutical, and mining industries, where they come into contact with aggressive chemicals and high temperatures. FFKM seals offer exceptional durability and long lifespan, which is particularly crucial in critical systems. Additionally, the material they are made of is characterized by low swelling, low permanent deformation, and low gas permeability.

Kalrez^® seals provide excellent resistance to a wide range of aggressive chemicals, including acids, bases, solvents, and gases. The material is resistant to over 1800 chemicals, ensuring high performance in aggressive process environments.

Kalrez^® rubber seals are resistant to oxidizing organic and inorganic acids, aliphatic and aromatic hydrocarbons, chlorinated solvents, strong acids and bases, oils, and oxidizing agents. They are designed to withstand the most challenging chemical conditions where other materials fail.

At Power Rubber, FFKM Kalrez^® seals are available in various formulations. Some exhibit extreme thermal stability, while others offer higher purity. We provide technical advice in selecting the appropriate compound based on temperature resistance, chemical compatibility, and application environment.

The operating range of FFKM seals ranges from -20°C to +327°C depending on the mixture. They provide reliable performance and chemical resistance in both low and high temperatures. These are the most chemically resistant elastomers available on the market, capable of withstanding extremely high temperatures. Additionally, they are resistant to thermal aging and corrosion. They do not degrade (crack, crumble, tear) even after prolonged exposure to high temperatures. Kalrez® seals are resistant to wear and friction, and heat does not compromise their resistance.

FFKM seals combine exceptional chemical and thermal resistance with flexibility and resistance to permanent deformation under compression. Thanks to their properties, they are an excellent choice in industries that require high durability and performance in demanding operating conditions.

Perfluoroelastomer seals provide long-term sealing and minimize the risk of unplanned maintenance due to seal failure. This is possible because FFKM seals are compatible with a wide range of aggressive chemicals - they do not corrode or degrade when in contact with chemical substances. Furthermore, frequent changes in pressure and temperature do not fatigue FFKM seals or lead to undesired medium leaks. Throughout their service life, perfluoroelastomer seals ensure high performance and sealing integrity. Due to their good resistance to mechanical loads and temperature stability, they do not crack, shrink, or lose their flexibility. This effective sealing solution protects against micro-leaks, reduces contamination and failures, and withstands high mechanical stresses that threaten the integrity of the seal.

Choosing FFKM seals from Power Rubber guarantees a reduction in costs related to unplanned downtime and maintenance costs.
