Canyon’s AF90BK00 is a 90 Shore A black AFLAS® (TFE/P) compound engineered for high-pressure and steam-exposed sealing applications where mechanical strength and chemical resistance are critical. It delivers excellent resistance to steam up to 200°C along with strong compatibility against amines, acids, and bases, making it well suited for steam-in-place (SIP) systems and aggressive process environments. With a service temperature range of -10°C to 232°C (15°F to 450°F), AF90BK00 maintains low compression set, high tensile strength, and dimensional stability under prolonged thermal and chemical exposure. The higher durometer provides enhanced extrusion resistance, supporting reliable performance in both static and dynamic high-pressure sealing conditions.

 

AF90BK00 meets ASTM D2000 M2HK910 requirements and is commonly used in chemical processing, energy, pharmaceutical, and industrial equipment where conventional elastomers degrade in steam or alkaline media. Its resistance to gamma radiation up to 200 MRad further supports use in sterilization, nuclear, and high-purity process environments. This AFLAS® formulation offers a dependable balance of durability, pressure capability, and long service life for demanding sealing applications.
