Plastic backing plate -  this kind backing plate is used by some manufacture, just because of the lowest cost to down the cost of flap disc.But this kind backing plate can not ensure the speed rotation , and could not supply highest strength , so we never use this kind backing plate for our export order ,unless customer need this kind backing plate according with his market.
