CR-2M

CR-2M is a rigid, semi-metal, molded friction material. It is composed basically of resins and rubber as a link system with frictional modifier agents, mineral fibres and fine copper shavings to enhance its strength. They help to establish the friction value by conducting heat from the operating surface. It is black with copper shavings. It has a medium and very stable friction coefficiency with low wear and excelent resitance to fading. CR-2M is fully cured material and is suitable for bonding and riveting.
