The abrasive layer consists of aluminum oxide mineral bonded to a 3 mil polyester film substrate using a durable resin system. At 12.0 micron grade, this sheet delivers controlled material removal suited to fine finishing stages where surface quality and dimensional accuracy are critical. Sheets measure 8.5 inches x 11 inches and are sold individually. Technicians in fiber optic connector finishing, roll superfinishing, and related precision machining operations rely on this film for consistent, repeatable results.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is commonly used in fiber optic finishing to polish ferrules and connectors to low-insertion-loss tolerances. It also sees regular use in roll superfinishing operations where tight surface finish specifications must be maintained. The PSA backing allows the sheet to be mounted securely to flat platens or backing plates without slipping during the polishing stroke. The 12.0 micron grade positions this sheet in the mid-range of the 266X series, which spans seven grades from 0.05 micron to 60.0 micron, making it suitable for intermediate stock removal before transitioning to finer finishing grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive mineral for consistent cut rate and long service life\u003c\/li\u003e\n  \u003cli\u003e3 mil polyester film backing provides dimensional stability during lapping strokes\u003c\/li\u003e\n  \u003cli\u003ePSA backing mounts securely to platens and flat fixtures without adhesive migration\u003c\/li\u003e\n  \u003cli\u003e12.0 micron grade suited to intermediate and fine finishing stages\u003c\/li\u003e\n  \u003cli\u003e8.5 inch x 11 inch sheet size compatible with standard flat-lap setups\u003c\/li\u003e\n  \u003cli\u003eApplicable to fiber optic connector polishing and roll superfinishing processes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in precision lapping and polishing applications including fiber optic connector finishing and roll superfinishing; compatible with flat platen lapping fixtures that accept PSA-backed sheet abrasives.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis film is applied by trade technicians and precision finishing specialists. Before mounting, ensure the platen or backing surface is clean and free of debris to achieve full PSA contact and prevent sheet movement. Peel and apply the PSA-backed sheet firmly to the work surface, smoothing from the center outward to eliminate air pockets. Follow the equipment manufacturer guidelines and any applicable workplace safety procedures when operating lapping machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: 3 mil Polyester Film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicron Grade\u003c\/strong\u003e: 12.0 Micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheet Size\u003c\/strong\u003e: 8.5 inches x 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144813346\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: 7000044801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345400201522,"sku":"7000044801","price":562.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534791.jpg?v=1782057137","url":"https:\/\/voomisupply.com\/products\/3m-7000044801-lapping-film-12-0-micron-psa-8-5x11-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
