MI 00 604 ................... download or print pdf
DESCRIPTION:
MI 00 604 is general purpose friction material suitable for light medium duty, wet and dry industrial applications. In recent years it has become a very well regarded material. It success may be attributed to its hardness which gives it good wear and tensile strength while still achieving average and stable friction levels.
SOME TYPICAL APPLICATIONS:
Various industrial applications.
Linings for tractor brake discs.
Low friction torque limiting and tension brake applications.
Industrial assembly applications..
ADHESIVES:
The use of any well known thermosetting adhesive is recommended.
