101mm x 45M Silicon Dioxide Lapping Film Roll – 0.2μm for Precision Glass, Semiconductor & Optical Finishing

The 101mm x 45M Silicon Dioxide Lapping Film Roll (0.2μm) is an extended-length high-production micro-abrasive roll designed for continuous industrial automated polishing machines, fiber optic termination lines, and semiconductor substrate fabrication.

Key Features

• Extended 45-Meter Industrial Roll (101mm x 45M / 147.6 ft): Provides continuous feed for automated optical polishing lines, reducing reel-change downtime and maximizing productivity.
• High-Purity Sub-Micron SiO2 (0.2μm): Tightly graded colloidal silica particles deliver defect-free, mirror-grade optical finishes with minimal subsurface damage.
• Uniform Mylar Film Substrate: Precision polyester film backing maintains uniform thickness, high tensile strength, and zero stretching under wet tension.
• Consistent Micro-Abrasion: Engineered to produce scratch-free, flat surfaces meeting stringent telecommunication and laser optical standards.

Recommended Applications

• High-volume automated fiber optic connector end polishing (telecom, datacom, and military spec connectors).
• Semiconductor wafer planarization and thin-section preparation.
• Laser optics, quartz crystals, optical filters, and precision window manufacturing.
• Faceting mirror polish on delicate and high-clarity gemstones.

Operating Guidelines

• Mount securely into continuous roll-feed lapping cassettes or reels.
• Run wet with deionized water or compatible polishing slurry for heat mitigation.
• Keep tension even across the 101mm width to ensure flat, uniform contact.
