CHEMFRICTION PHENOLIC RESIN
Friction Phenolic Resin is thermoplastic phenolic resin, modified phenolic resin formed by polycondensation of phenol and formaldehyde under the action of acid catalyst. has the characteristics of low free phenol content, high thermal decomposition temperature, low high-temperature thermal decay, good fluidity, strong infiltration ability to fibers and fillers, stable friction coefficient of products, strong thermal recovery ability and low wear.
Usage in disc brake pads, drum discs, clutch discs, brake bands, friction blocks, steel backing rubber, train brake shoes and industrial brake shoes on automobiles.
