Polishing Chalk is specially formulated exclusively for use in rubber roller industry. It is a high performance chalk with finer texture and 30 ShoreA durometer. It is filtered to remove any contamination making this an extremely pure Chalk that is gentle on the rubber surface.
In use there is only low ambient dust release, making it much safer and healthier for the environment and employees.
Polishing Chalk is used to identify uneven areas on a rubber roller during the grinding process. It identifies “pin-holes” in the surface as the dust is fine enough to fill and highlight them. Microscopic Rubber dust combines with the Chalk to make small balls which leaves a much cleaner surface than just wiping alone.
The chalk aids lubrication and reduces friction and heat without clogging fine abrasives when the surface is being polished, keeping the integrity of the rubber surface intact.
