MC140
MC140 is a rigid, semi-metallic, moulded material. It is a resin based material, and it uses rubber powder as a linkage, along with friction modifier agents, mineral fibers and fine copper shavings to enhance its strength. It has high temperature dissipation capacity from the operating surface, due to a very special phenolic resin designed to work and deal with high temperatures. MC140 has a high and very stable friction coefficient, and excellent resistance to fading, which makes it perfect for high performance applications such as racing brake pads for cars and bikes. MC140 is a fully cured material and is suitable for bonding & riveting.
