Friction Dust is a products used as additive in Manufacturing of Friction Material (Automotive & Industrial) like Brake Linings, Disc Brake Pads, Railway Brake Blocks and Clutch Facings etc to stabilize the friction level.
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.
Properties:
Friction Dust have a resilient nature which cushions the engaging property of a piece of lining. In addition, they decompose on the surface of a lining at various elevated temperatures which controls the wear and offers a protective device by prohibiting excessive temperature from being developed. The inclusion of friction dust in the composition of the brake lining friction material also helps control brake noise.
Application:
Cashew Friction Dust is as common ingredient of friction linings formulations. Friction Dust represents up to 20% by weight of friction elements used in manufacturing of brake lining, brake pads, brakes shoes, railway block and clutch facings where high absorption and frictional properties are needed. Friction dust of various mesh sizes is supplied according to requirements of various manufacturers for making Brake linings and clutch facings which are used in the friction formulations to be used in metallic, semi-metallic and non asbestos brake products.
