It features aluminum oxide mineral coating bonded to a 3 mil polyester film substrate with a pressure-sensitive adhesive (PSA) backing. At 0.30 micron grit size, this sheet delivers ultra-fine material removal suited to the last stages of connector end-face preparation. The sheet measures 8.5 inches x 11 inches and is sold individually. Fiber optic technicians and communications infrastructure professionals use this film where consistent, repeatable surface finish is critical to minimizing insertion loss and back reflection.\u003c\/p\u003e\u003cp\u003eThis lapping film is intended for polishing fiber optic connector end-faces in both field and bench applications. The PSA backing allows the sheet to be mounted flat to a polishing plate or fixture without slipping, maintaining consistent contact during the polishing stroke. It is well suited to single-mode and multimode connector termination workflows where surface finish requirements are tight and abrasive progression through multiple micron grades is standard practice.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.30 micron aluminum oxide mineral for ultra-fine finish polishing\u003c\/li\u003e\n\u003cli\u003e3 mil polyester film backing provides dimensional stability during use\u003c\/li\u003e\n\u003cli\u003ePSA backing secures sheet to polishing plate or fixture without adhesives or clips\u003c\/li\u003e\n\u003cli\u003e8.5 inches x 11 inches sheet size fits standard polishing fixtures and pads\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for fiber optic connector end-face polishing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in fiber optic connector polishing workflows as a fine-grit finishing sheet; intended for use with flat polishing plates or fixtures that accept PSA-backed lapping film sheets.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis product is applied by a fiber optic technician or communications tech during connector termination or refurbishment. Press the PSA side firmly onto a clean, flat polishing plate or puck before use to eliminate air pockets. Inspect the film surface before each use and replace when mineral loading or surface damage is visible. Follow the connector manufacturer polishing procedure for proper stroke count and load when using this grade in a multi-step abrasive sequence.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit Size\u003c\/strong\u003e: 0.30 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral Type\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\u003eBacking Type\u003c\/strong\u003e: Pressure-sensitive adhesive (PSA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheet Dimensions\u003c\/strong\u003e: 8.5 inches x 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7000044823\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344063922482,"sku":"7000044823","price":1267.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524038.jpg?v=1782028055","url":"https:\/\/voomisupply.com\/products\/3m-7000044823-lapping-film-268x-0-30-micron-psa-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
