What is the best way to store Flap Discs?

The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in Flap Discs are sensitive to changes in temperature and humidity. They are best stored at temperature levels of 16 to 27ºC. Flap Discs should be kept in their cartons until you are ready to use them, and the cartons should be kept away from heat sources, cold walls, and off of damp floors. Rotate stock and use flap discs on a first in, first out basis.
