DESCRIPTION:
Using MI 00 601 as the base material, this has been developed for more specialized applications where safety and continuous operation are important issues.
The key differences between this material and (MI 00 601) is the high graphite content. Acting as a dry lubricant, this graphite servers to greatly reduce wear, and narrow the gap between static and dynamic friction coefficients which has particular interest in torque limiting and tension brake applications.


SOME TYPICAL APPLICATIONS:
Friction torque limiting and tension brake applications.


ADHESIVES:
The use of any well known thermosetting adhesive is recommended.
