Cashew Friction Dust

CNSL friction particle is used in disc pad brakes and drum linings as a stabilizing agent. These particles (sometimes called friction dust) have a resilient nature which cushions the engaging property of a piece of lining.

Friction Dust is crossed linked product obtained from the reaction of Cashew Nut Shell Liquid with different aldehyde donors like Formaldehyde / hexamine / Para Formaldehyde to achieve the desired Friction dust properties.

Basically it is a phenol formaldehyde resin, which is polymerized and reacted with any one of the aldehyde donors and made to powder form of various standard mesh sizes.
