MI 00 501 ................... download or print pdf 

DESCRIPTION:
With the experience and technology used in moulded materials MI 00 501 contains many complementary types as short cut fibres, with improvements in its cement, is a material with very good mechanical and frictional characteristics.

MI 00 501 is capable of withstanding higher shear and tensile forces.


SOME TYPICAL APPLICATIONS:
Toothed/ geared friction discs.
Agricultural torque limiting devices, etc.


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