Product Data Sheet
Rockbrake® RB220-Roxul®1000
Engineered mineral fibre (Note Q) for application in friction materials
Rockbrake® RB220-Roxul®1000 is a premium quality engineered mineral fibre. Its surface treatment gives an
optimum bond with phenolic resins resulting in better reinforcement properties under extreme braking conditions.
The percentage of non fibrous material > 125 microns is with a maximum of 0.2% very low.

ADVANTAGES OF ROCKBRAKE® RB220-ROXUL®1000:
-
Rockbrake® RB220-Roxul®1000 also positively influences the following parameters :
- material wear
- noise and vibrations
-
Rockbrake® RB220-Roxul®1000 is consistent in quality in terms of :
- chemical composition
- surface treatment
- purity
- fibre length
-
Using Rockbrake® RB220-Roxul®1000 gives formulators the opportunity to decrease the use of other fibres
in the matrix (aramid, steel, glass, ceramic, copper, brass), resulting in significant cost savings on a price per
volume base.
