SF2420

Flexitallic SF2420 is a sheet sealing material that is free of asbestos, crafted with an SBR (Stene-butadiene rubber) base, and fortified with synthetic fibers. This material is suitable for a wide range of applications, including hot and cold water, steam, oils, fuels, gases, and various general chemicals.

SF2420 is distinguished by its specialized formulation designed to expand in a controlled way when it comes into contact with oil. This unique feature makes it especially suitable for automotive applications or situations where lightly loaded connections need to be sealed against oil-based substances.
