SFD
SFD is green rigid friction material which consists phenol resins as a bonding system, short fibres, friction modifiers and fillers. This offers a medium high static coefficiency and an excellent mechanical resistance, very successful for wind turbine components. SFD is fully cured and suitable for bonding and riveting.
