Application: Especially suitable for removing heavy rust on metal surfaces and removing paint; especially suitable for grinding and surface treatment of cement concrete and grinding treatment of brittle materials such as stone and glass.

Features: It makes up for the weak points of ordinary rigid paper sand discs such as easy to break and easy to deform due to moisture. Special high-quality engineering plastics are used as the matrix to increase product strength,enhance anti-centrifugal force and anti-destructive force, and prevent moisture and deformation.
