Suggestions:
Ø  When the polyurethane polishing pellets are bonded to the rigid mould, it is suggested to use the special bond for polyurethane made by our company.
Ø   When the polishing ability is decreased due to the extension of processing time, it is suggested to brush the polyurethane polishing pellets with soft wire brush from time to time.
