SA80/25
SA80/25 is a non-asbestos and moulded friction material. With a low friction coefficient and good resistance against wear. It is composed basically of resins as a link system with frictional modifier agents and mineral fibres to enhance its strength which helps to establish the friction coefficient value. It is black. It is a fully cured material and is suitable for both bonding and riveting.
