Overview
3M EMSD Diamond Lapping Film Type H is a high-performance polishing abrasive designed specifically for demanding fiber optic connector processing. This film utilizes micro-graded diamond minerals bonded to a precision-engineered 3 mil polyester backing, ensuring consistent material removal rates and superior surface finishes on fiber end-faces.
Engineered with a tougher resin system and higher diamond concentration compared to standard films, Type H is optimized for cutting and polishing hard materials, including ceramic, stainless steel, plastic, and composite ferrules. Its uniform construction provides predictable, repeatable results, making it an essential component for achieving high-yield connector manufacturing and maintenance.
