What is MRF?

MRF IS THE SECRET BEHIND OUR RHEOSHOX TECHNOLOGY

IT’S HOW WE ARE ABLE TO CREATE THE SMARTEST DAMPER SYSTEM ON THE MARKET

BUT WHAT IS MRF, AND WHY IS IT SO IMPORTANT?

MRF or MR Fluid is short for Magneto-Rheological Fluid.

It is a smart liquid that consists of a mixture of fine magnetizable particles (typically iron) and a carrier fluid (e.g., oil or glycol).

The iron particles contained in the fluid are between 1 to 10 microns in size.

A human hair, in comparison, has a diameter of 50-70 microns.

FASTER THAN THE BLINK OF AN EYE

When MRF is exposed to a magnetic field, the iron particles in the fluid link and change the MRF from a liquid to a semisolid.

This change occurs in less than 0,5 milliseconds, more than 200 times faster than the blink of an eye.

Once the magnetic field is removed, the MRF reverts to its liquid state.

FULLY ADJUSTABLE & INCREDIBLY ACCURATE

The degree of change the MRF undergoes when exposed to a magnetic field is related to the magnetic field’s strength.

The stronger the magnetic field, the higher the yield stress of the liquid.

Therefore, the MRF’s level of stress resistance can be controlled very accurately by varying the magnetic field’s intensity.

This has made MRF the ideal technology for applications, such as brakes, suspensions, dampers.

Yield Stress vs. Magnetic Field Strength

PROVEN OVER TIME

While smart liquids such as MRF are new to most people, the MR technology has proven itself for over 20 years in the automotive industry in suspensions or steering systems, most prominently in the Audi’s® suspension system of the TT or R8 models.

MRF dampener systems can also be found in the construction or medical industry.

But no other system can compete with the performance of RHEOSHOX.
