What backing plate material should you choose for your flap disc?
All flap discs are a combination of abrasive flaps adhered to a rigid backing plate. It is the backing plate that provides stability during operation. There are 3 main material types:
1. Fiberglass: This material is most popular because of its high strength and lightweight. These plates help absorb vibration and are consumed during use, with no smearing.
2. Plastic: This backing type is becoming more popular due to some conformability as well as being trimmable. This allows more use of the flaps, especially for blending and finishing.
3. Aluminum: These are the least popular, but are good in applications demanding extra high strength and rigid support. While not consumable during use, an aluminum plate can be recycled.
