It uses a silicon dioxide (silica mineral) abrasive coated onto a 3 mil flexible backing, delivering consistent surface finish and controlled material removal at the end of the polishing sequence. The disc is engineered to hold tight protrusion tolerances, which directly supports low insertion loss and low back reflection in finished fiber connections. Fiber optic technicians and assembly professionals handling connector termination and end-face preparation are the primary users of this product.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for bench-top and automated fiber optic polishing machines across multiple equipment brands. It is used in telecommunications, data center cabling, and fiber assembly environments where end-face geometry and surface quality of ceramic ferrules must meet strict optical performance standards. The 5-inch diameter format fits a wide range of polishing machine platens used in both production and field termination workflows. It is sold individually and is available in larger format sheets and rolls for high-volume operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon dioxide abrasive on a 3 mil backing delivers controlled, consistent material removal for final-step polishing\u003c\/li\u003e\n  \u003cli\u003eConsistent protrusion values support repeatable connector end-face geometry across high-volume runs\u003c\/li\u003e\n  \u003cli\u003eLow insertion loss and low back reflection results in finished ceramic ferrule connectors\u003c\/li\u003e\n  \u003cli\u003eCompatible with many brands of fiber optic polishing machines for broad equipment flexibility\u003c\/li\u003e\n  \u003cli\u003eAvailable in disc, sheet, and roll formats to match different production volumes and machine types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with many different brands of fiber optic polishing machines that accept a 5-inch diameter polishing disc.

Before mounting or replacing a polishing disc, power down the polishing machine and allow any rotating components to come to a full stop. Follow the polishing machine manufacturer's guidance for disc mounting, alignment, and fluid or film application. Dispose of used abrasive discs according to applicable facility waste handling procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Dioxide (Silica Mineral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Thickness\u003c\/strong\u003e: 3 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.71 inches x 6.88 inches x 4.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111562345\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000044736\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346968478002,"sku":"7000044736","price":2211.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524414.jpg?v=1782095386","url":"https:\/\/voomisupply.com\/products\/3m-7000044736-polishing-disc-5-inch-silicon-dioxide","provider":"Voomi Supply","version":"1.0","type":"link"}
