• Cloth Backings – There are two types of cloth backing available. Cotton backing is flexible and lightweight, but not waterproof. Polyester backing is stronger than cotton. It is waterproof, fray resistant and absorbs shock. Cloth backings come in various weights. • Fibre Backings – Fibre is a hard, durable material with great mechanical strength. It is used to make resin fibre discs. • Paper Backings – Different paper weights, designated by letters, are available for different applications.
