Molub-Alloy BioTop 9418

Biodegradable wheel flange and switch plate grease



Description

CASTROL MOLUB-ALLOY™ BIOTOP 9418 wheel flange and switch plate grease is formulated on the basis of a synthetic

ester and is readily biodegradable according to CEC L-33-A-93 (> 85 %). A selection of high quality additives provides for

outstanding friction and anti-wear properties of CASTROL MOLUB-ALLOY™ BIOTOP 9418. Leading manufacturers of

central lubrication systems have confirmed the excellent pumpability in equipment used for wheel flange and switch plate

lubrication.

CASTROL MOLUB-ALLOY™ BIOTOP 9418 is formulated from a synthetic ester and an inorganic thickener.

CASTROL MOLUB-ALLOY™ BIOTOP 9418 wheel flange and switch plate grease was developed according to

specifications of Deutsche Bahn AG (German Railways).

Application

CASTROL MOLUB-ALLOY™ BIOTOP 9418 has been especially developed for the lubrication of wheel flanges and switch

plates with suitable central lubrication systems.

Advantages

Readily biodegradable > 85 %

CASTROL MOLUB-ALLOY™ BIOTOP 9418 provides for a stable lubricating film and excellent corrosion protection

due to its good adhesive properties and its water stability.

High quality additives provide for outstanding friction and anti-wear properties.

The biodegradability and the reduced consumption rates help to protect environment and resources.

Spray tests at leading manufacturers of lubrication equipment showed a homogeneous spray pattern at 4 - 6 bar

pressure, depending an the number of spray nozzles.
