Plastic Backed Flap Disc

Flap disc with rigid plastic backing, high rigidity without deformation, stable vibration-free high-speed grinding for smooth surface.
Brown aluminum oxide & zirconia abrasives optional, strong cutting power to remove weld slag, rust, burrs and oxide layer efficiently.
Lightweight wear-resistant backing offers good heat dissipation, less overheating and workpiece burning during long-time operation.
Full range of diameters, grits and bore sizes, custom specifications available, neutral export packages and OEM private label service supported.
Compatible with angle grinders, widely applied in steel structures, hardware stampings, auto parts and stainless steel sheet flat grinding & rust removal.

Our Plastic Backed Flap Discs adopt high-rigidity flexible plastic base instead of traditional fiberglass or iron backing, featuring lightweight, high toughness and excellent bending resistance. The premium plastic backing delivers stable structural support during high-speed grinding, effectively avoiding cracking, deformation and warping that commonly occur on conventional flap discs, ensuring safer and smoother operation.

Equipped with uniformly arranged high-quality abrasive flaps, the disc retains outstanding self-sharpening performance and fast stock removal capability. It balances efficient grinding and fine finishing perfectly, capable of quickly removing weld spots, burrs, rust, oxide layers and surface flaws. Meanwhile, the flexible plastic base allows perfect fitting on flat, curved and irregular workpiece surfaces, achieving zero dead-angle polishing and uniform surface texture.

Plastic Backed Flap Disc

This flap disc generates low grinding heat and features great heat dissipation performance, effectively preventing workpiece burning, discoloration and scratch marks during continuous heavy-duty work. The tightly bonded abrasive flaps ensure no shedding or loosening in long-term operation, greatly extending the service life compared with ordinary abrasive discs. The special anti-clog coating also resists dust and metal debris accumulation to maintain consistent grinding efficiency.

Lightweight design reduces machine load and worker fatigue, making it ideal for both manual and mechanical grinding operations. It is widely suitable for surface polishing and finishing of stainless steel, carbon steel, aluminum alloy, hardware and metal fittings. We offer full grit ranges and complete standard sizes, and support custom specifications, logo printing and OEM packaging. As a professional manufacturer, we provide stable quality control, competitive factory price and fast bulk delivery for global customers.
