The right fluid for your application

Introducing BASF

BASF is the worlds largest and most successful chemical company, with a history of innovation that stretches back almost 150 years. In that time, we have gained a hard-won reputation as a respected and trustworthy partner for many world leaders in industry.

In recent years, we have witnessed markets becoming ever more competitive while operating profits and margins are squeezed tighter than ever before. In response to this situation, we have increasingly been working as strategic partners with our customers, helping them to achieve maximum value from their operations.

This activity has included taking a proactive approach to problem solving, as well as pioneering new products that unlock potentially valuable new revenue streams.

Magnetorheological Fluids (MRFs)

Magnetorheological fluids are a good example of how BASF innovates to meet

new challenges and to open up new commercial opportunities.

MRFs are liquids displaying flow properties that can be adjusted by the introduction

of magnetic fields. As a result, their characteristics can be changed from free

flowing to solid in just milliseconds.

This property allows for the design of mechanical devices for adaptive force and

torque transmission to become highly-dynamic and cost efficient. In this way,

MR-devices can work at the extreme edge of efficiency, creating added value for

end-users and strengthening the margins of manufacturers.

Typical applications of MRFs

The unique flow properties of MRFs make them particularly

well suited to many applications that involve the adaptive

transmission of high forces. These typically include brakes,

couplings, dampers, mounts and bushings.

MRFs are not only able to transmit high forces, but can

change their physical properties extremely quickly, from liquid

to solid and back again in milliseconds. This enables these

fluids to perform tasks that were previously carried out by

mechanically complex components, thus simplifying design

and reducing costs.

Basonetic MRF

BASFs own range of magnetorheological fluids is known by

the trade name Basonetic. Basonetic MRF are manufac-

tured entirely by BASF, using our own Carbonyl Iron Powder

(CIP) ingredients in processes that we pioneered. This gives

us complete control of the product properties and enables us

to guarantee our customers a flawless product.

The other great advantage of maintaining full control of the

product properties and production process is that we can offer

individual formulations that precisely meet our customers

requirements. Depending on the working mode of the device for

which you need a MRF, we can formulate a perfect solution to

deliver exactly the results you want.
