To use with a resin fiber disc on an angle grinder, put it on.
Polypropylene is a strong pad.
It was made to hold the disc in place and be flexible enough to let the disc move with the material being sanded.

The max RPM is 13,300.
The style is standard. In this case, the size is 4 1/2 x 5/8 -11.
The backing pads from Mercer Industries are made to support its different discs, like psa discs, hook and loop discs, quick change discs, and fiber discs. They work with angle grinders, die grinders, and orbital sanders. With the best raw materials, this disc is strong enough to hold the disc in place and flexible enough to let the disc move with the material being sanded. All discs must be used with a back pad.
The first time I used it, the rubber came apart from the center and flew away. The unit felt great. It’s very dangerous. Returning both of the things I bought right away because I didn’t want to risk having another one do the same thing.
