Cashew Friction Dust (CFD)

We are supplier of this product.
Friction Dust is made from cashew nut shell liquid, used in metallic, semi-metallic, non-asbestos organic (NAO) and asbestos formulations for brake linings, disc pads, clutch facings and brake blocks
Friction Dust improves wear and fade resistance, decomposing at various elevated temperatures thereby providing good flexibility and thermal stability in friction materials.
NSL friction particle is used in disc pad brakes and drum linings as a stabilizing agent. These particles (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.
Application
It is mainly used as on of the prime raw material for heavy automobile non-asbestos and asbestos brake lining. It is also used in clutch facing and disc pad.
