CH-FF7521 High-Temperature Perfluoroether Rubber (FFKM) for Air Compressors
Product Overview
CH-FF7521 is a premium perfluoroether rubber (FFKM) compound developed with triazine vulcanization, offering superior high-temperature resistance and chemical durability. Engineered to match Kalrez®7075, it ensures minimal compression permanent deformation, exceptional thermal stability, and excellent airtightness, suitable for both static and dynamic sealing applications.
Ideal for the air compressor industry, as well as aerospace, petrochemical, and oil drilling applications, CH-FF7521 provides reliable sealing even under extreme thermal and chemical conditions.
Key Features
· High Temperature Resistance: Continuous operation up to 315°C, maintaining integrity under thermal cycling.
· Excellent Chemical Resistance: Compatible with a wide range of chemicals, acids, alkalis, and mixed media.
· Minimal Compression Set: Outstanding permanent deformation resistance, ensuring long-term sealing reliability.
· Dynamic & Static Sealing: Suitable for O-rings, gaskets, and custom sealing components.
· Durable Mechanical Properties: Maintains tensile strength, elongation, and hardness under high temperature.
· Industry Applications: Air compressors, petrochemical plants, aerospace components, oil drilling equipment.
