Improved Friction Performance by using Highly Porous, Thermally Stable Particles; Promaxon
A porous calcium silicate by the name of Promaxon®-D has been
widely used in friction materials. Especially in NAO/non-steel
(ceramic) disc pad applications, Promaxon®-D is an important
ingredient of new generations of formulations. Except for its
ability to increase porosity, the effect of Promaxon®-D on the
friction performance was not well understood. This paper describes
the effect of Promaxon®-D on the most relevant friction parameters
of NAO/non-steel disc pad formulations.
Promaxon®-D is a material which has been observed to be very
effective at increasing the compressibility of friction materials.
When added in the right percentage, Promaxon®-D can also be
beneficial for parameters like friction level, fade resistance and
recovery. This makes Promaxon®-D a versatile raw material for
NAO/non-steel disc pad applications.
