12000RPM Fiberglass Sanding Disc Backing Pads 100mm 180mm

Product Specification

manufacture directly sale high quality fiberglass backing pad for making flap disc

Introducing our premium Fiberglass Backing Pad, the essential core component engineered for the production of high-durability, high-performance flap discs. Designed for abrasive tool manufacturers and professional fabricators, this backing pad provides the critical foundation that determines the final product's safety, efficiency, and lifespan. Manufactured with precision and sold directly from our factory, we guarantee superior quality, exceptional consistency, and unbeatable value.

Core Features & Advantages

• Uncompromising Material & Construction: Made from layered, reinforced fiberglass resin composite, our pad offers exceptional structural integrity. It is rigid yet retains slight flexibility, effectively resisting cracking, warping, and shattering under high-speed operation and heavy loads.

• Exceptional Heat & Chemical Resistance: The fiberglass composite inherently withstands high temperatures generated during prolonged grinding without degrading. It is also resistant to moisture, oils, and common solvents, ensuring stable performance in various working environments.

• Precision-Molded Design: Each pad features a perfectly centered and reinforced arbor hole (sized to your specifications, e.g., 7/8" for angle grinders) and a flat, uniform surface. This ensures smooth, vibration-free running (excellent balance), easy assembly of flap sections, and consistent grinding results.

• Optimized Surface for Maximum Bonding: The surface is specifically treated or textured to create an ideal substrate for adhesive bonding. This guarantees a powerful, permanent bond between the backing pad and the abrasive cloth flaps, virtually eliminating the risk of flap detachment during use.

• Enhanced Safety & Long Service Life: Engineered for safety, our pads are built to handle high RPM ratings, reducing the risk of catastrophic failure. Their durability means the flap disc's lifespan is determined by the abrasive flaps themselves, not by a failing backing pad.

• Available in Standard & Custom Sizes: We offer a full range of standard diameters (e.g., 4", 4.5", 5", 7") and thicknesses to suit various flap disc profiles and applications. Custom sizes, hole specifications, and surface treatments can be accommodated for OEM clients.

Technical Specifications (Example)

• Material: Reinforced Fiberglass Composite Resin

• Color: Typically Brown or Green
