AF 450

The asbestos-free fiber material AF 450 is the top-quality material for maximum steam resistance.

AF 450 is a carbon fiber-based sealing material for steam and high-temperature applications. Thanks to its optimized fiber-matrix structure, the seal remains permanently elastic and leak-proof even under fluctuating thermal loads. AF 450 is used wherever conventional fiber materials reach their limits, for example, in steam turbines, district heating stations, and chemical reactors.
