Sanding blocks, also known as polishing blocks, resin blocks, or plastic blocks, use sponge as the base material with abrasive grit embedded in the sponge. They are a type of grinding and polishing material used for curved surface grinding. They have strong water absorption and can maintain wet grinding for extended periods, serving as an alternative to wet sandpaper. Sanding blocks can be made into various shapes and sizes. They are suitable for polishing curved, arched, and 3D surfaces of metals or magnesium-aluminum alloys, treating metal rust stains, hand-sanding furniture, polishing the surface of plastic products, and sanding during automotive repair and paint touch-ups. They possess notable characteristics such as water resistance and resistance to acids and alkalis.
Applications of sanding blocks
Sanding blocks are suitable for polishing various metal or magnesium-aluminum alloy curved surfaces, arc surfaces, and 3D surfaces. They are also used for surface treatment of metal rust stains and plastics, woodworking, furniture sanding, plastic product surface polishing, sanding of car repair and paint touch-up areas, and polishing of products such as amber and beeswax.
Sanding block product features
