MI 00 704 ................... download or print pdf
DESCRIPTION:
The MI 00 704 is a new material of slight friction but great resistance destined mainly to applications of competition that work as much in dry as in oil bath. Nevertheless its great benefits allow to use it in automotion as well as industrial applications.
Developed from a revolutionary formula, this material has an excellent coefficient of friction, wears away minimum, smoothness of operation and stability.
Even to high temperatures. It is an effective material to reduce the noise level during the work.
SOME TYPICAL APPLICATIONS:
For racing competition, automation, heavy vehicles and industrial applications.
ADHESIVES:
The use of any well known thermosetting adhesive is recommended.
