The A/O P120 Sponge Sanding Roll is an aluminum oxide abrasive roll laminated with a foam layer. It is used for manual sanding, sanding block use, contour sanding, edge sanding, coating preparation, and surface finishing.
Aozhong supplies this A/O P120 Sponge Sanding Roll for distributors, abrasive converters, woodworking factories, automotive repair suppliers, and industrial users who need roll-format foam-backed abrasive material.
The working side uses aluminum oxide grain. The reverse side uses foam backing rather than hook and loop backing or PSA adhesive. The roll can be used directly by hand, wrapped around a sanding block, or converted into sanding pads and sheets.
P120 is a FEPA coated abrasive grade used for surface leveling, wood sanding, primer sanding, paint preparation, and sanding between process stages. FEPA P-grades are used for coated abrasives such as sandpaper and sanding rolls.
Aluminum oxide P120 sponge sanding roll is designed for medium surface preparation, hand sanding, edge finishing, and contour sanding before progressing to finer grits.
Suitable for preparing wood-based surfaces before sealer, primer, paint, or other coating processes.
Used for medium sanding stages where controlled surface leveling is required before finer refinishing steps.
The sponge backing adapts to shaped surfaces and helps maintain more even sanding pressure during hand operations.
Suitable for controlled surface preparation before coating, bonding, painting, or subsequent finishing processes.
The roll format supports flexible conversion into practical sanding consumables for distributors, workshops, and OEM abrasive programs.
P120 is generally used for medium sanding, surface leveling, and preparation before moving to finer grit stages. It is more suitable for controlled preparation than final polishing or ultra-fine finishing.
The aluminum oxide abrasive layer removes material from the workpiece surface. The foam layer acts as a pressure buffer between the abrasive and the workpiece.
When sanding curved edges, contoured surfaces, protrusions, recesses, and irregular workpieces, foam-backed sanding rolls conform more closely to the workpiece’s contours than flat sandpaper.
The foam backing also reduces direct pressure concentration from the operator’s hand or the sanding block. This helps minimize edge cutting and indentations during manual sanding.
P120 is typically used after coarse sanding and before fine sanding. It can be used for primer preparation, leveling wood surfaces, sanding painted surfaces, and removing sanding marks left by coarse-grit sandpaper.
Each layer is designed to support controlled sanding, stable abrasive retention, flexible contour contact, and practical roll dispensing or conversion.
Aluminum oxide grain for sanding and surface preparation.
Resin bond for secure grain anchoring during sanding.
Paper or flexible composite backing depending on product construction.
Sponge backing for pressure distribution and contour contact.
Paper core for storage, dispensing, and abrasive conversion.
