Overview
The 3M-EMSD Aluminum Oxide (A/O) Polishing Discs are precision-engineered abrasive films designed for high-performance fiber optic connector polishing. These 4-inch discs utilize a uniform coating of aluminum oxide mineral on a stable polyester backing, ensuring consistent material removal and surface finish quality across the entire surface of the disc.
Ideal for data center, laboratory, and production environments, these discs are specifically optimized for non-slurry processing, which helps to reduce overall process time while maintaining high production yields. Their durable construction supports long abrasive life, making them a cost-effective choice for connector termination procedures.
