CR3HP is a severe service high performance synthetic sintered metallic friction material that outperforms OE premium and aftermarket service heavy duty ceramic and semi-metallic pads. It is specifically designed for on and off road racing, where no burnishing or bedding in is required. CR3HP advantages are derived from its ability to conduct heat away from the brake interface surface. The porosity caused by the finely granulated metallic and graphite particles, welded together in a matrix, allows air to circulate in the micro-pockets of the matrix. The macrostructure of the matrix is designed for both brake pad and brake rotor durability. The absence of phenolic binding resins means CR3HP pads are completely inflammable.
