3M EMSD A/O Polish Disc 4 inch 0.05um (50pk)

Overview

The 3M EMSD Aluminum Oxide (A/O) Polish Disc is designed for high-precision fiber optic connector polishing. These 4-inch discs feature tightly graded aluminum oxide mineral particles, which provide consistent and uniform abrasion for demanding telecommunications and data center applications.

Engineered for dry-process compatibility, these polishing films help minimize environmental impact while maintaining high throughput. They are constructed with a durable polyester film backing to ensure stability during the polishing cycle, promoting reliable surface finishes and high connector yield rates.

Key Features

• Aluminum Oxide Abrasive
  Uses high-quality mineral coating for consistent material removal and smooth surface finish.
• Polyester Film Backing
  Provides excellent structural integrity and tear resistance during operation.
• Optimized Particle Size
  Features 0.05um grading for final polishing stages to achieve low back-reflection requirements.
• Non-Slurry Processing
  Enables dry polishing, reducing the need for cleaning solvents and associated waste management.
• Efficient Process Time
  Designed to minimize cycle times in production environments without sacrificing quality.
• High Yield Potential
  Consistent abrasive distribution leads to fewer connector reworks and failures.

Applications

• Fiber optic connector end-face polishing
• Telecommunications network assembly
• Data center cabling termination
• Laboratory fiber preparation
