△Metallic Sulphides
important compounds for
friction material in general, working as lubricants and friction
stabilizers.
Because of their regulating
properties and their inherent condition of lubricity, the use of
metallic sulphides improve the characteristics of rotor and pad
wear in high temperatures, pressure and speed, giving an
efficient and softer braking, with lower vibrations.
△Oxides
Highly used in the pad
industry, oxides are friction materials that normally provide
high friction coefficients.
△Metal
Powders
The use of metallic powders in
the friction materials is justified basically by their important
characteristic that enables good braking performance: heat
dissipation. Some materials show additional characteristics due
to their physical properties and grain morphology, for instance,
rotor protection and pad mechanic resistance.
△Special
Compounds
Catalise has been developing
friction products that combine some desirable characteristics in
friction material, such as high friction coefficient and more
protection to the brake rotor.
