Rogers NITROPHYL Floats contain NITROPHYL Closed Cell Foam that uses a proprietary NBR compound to provide excellent resistance to most fuels and chemicals, making it ideal for use in level sensor applications.

NBR Float provide superior chemical resistance and buoyancy in a wide range of fluids, especially new alcohol blended fuel mixtures (cf. liquid compatibility guide). Such shapes as tubes, rods and magnets can be affixed to the float, when necessary.

The closed cell nature eliminates the possibility of sudden catastrophic failure of float sinking down to the bottom, typically associated with alternative materials based floats. NBR float is transformed from a solid material to a hard(ebonite-like), cellular structure by …

Floats are closed pore foam devices composed of NBR rubber and phenol resin. They are excellent in terms of oil resistance and dimensional stability. NBR: Ebonite containing a large amount of cross-linking agent (sulfur).*

The MS01-NBR Series Magnetic Float ring actuator magnet (excentric) have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Suited for stems with an outer diameter up to 7.5mm; float is foam.

Rogers Nitrophyl® NBR floats have been specifically designed to resist petroleum based liquids such as gasoline, liquid propane and motor oil, but are also resistant to a wide variety of other substances.

Spansil ® is our NBR expanded Ebanite formula with cells cross 100% impermeable to liquid. Spansil ® is our transformation process and it has been the world leader in the special tech float production for over 50 years .

Choose from various styles, dimensions and buoyant materials such as Polyamide (PA), Polypropylene (PP), Nitrile Butadiene Rubber (NBR) and Stainless Steel (V2A) depending on your application.

Rogers’ NITROPHYL® NBR floats address these challenges as a crucial element of the solution. By using Rogers’ reliable, closed cell NBR float technology, sensor manufacturers can accurately and effectively detect leaks, separation and changes in …
