PRODUCT FAQ

What is the 3M™ Microfinishing Film 5MIL Type UK Belt used for?

The 3M™ Microfinishing Film 5MIL Type UK Belt is primarily designed for refining micro-abrasive surfaces on precision components such as optical fiber connectors, medical instruments, and semiconductors.
Can I use this belt for hand sanding or does it require special equipment?

This product requires machinery that is specifically designed to operate with its abrasive properties.
How many belts come in each case of the 3M™ Microfinishing Film 5MIL Type UK Belt?

There are a total of fifty (50) belts per case with ten (10) inner cartons included.
Is there any particular type of motor required to run this sheet?

We recommend using motors producing roughly 1725 RPM - higher speeds may cause the abrasive material to weaken faster than desired results.
What makes these products special, and why should I purchase them over other brands available in the market today?

The proprietary formulation allows for microfine finishing along with fast cutting action resulting into an overall improved finish quality accompanied by less labor-intensive application procedures.

Aluminum Oxide Mineral

3M™ Microfinishing Film Belt 272L is a unique abrasive belt designed for sheet polishing, finishing, and flat finishing. The belt is made by anchoring aluminum oxide mineral to a polyester film backing with resin. Aluminum oxide mineral is a popular choice among industrial professionals due to its fast cut rate and long life. The mineral's hardness, strength, and low heat retention help the belt withstand the repeated wear that grinding and finishing often demand.

Water-Resistant Polyester Backing

The polyester film backing on 3M™ Microfinishing Film Belt 272L is water-resistant, allowing the belt to be run wet or dry. By applying a lubricant, like water, as the abrasive runs, operators may be able to wash away swarf and debris that tend to clog the abrasive or warp and discolor the substrate. The resin bond that fastens aluminum oxide to the backing helps the abrasive stay cool, because it breaks down gradually as the belt rotates.

Available in a Range of Grades

3M™ Microfinishing Film Belt 272L is available in a versatile range of grades, from 9 to 100 micron. Operators can select the right grade for their unique application. Higher grades, like 100 micron, are good for higher removal processes, while lower grades, like 9, are good for final, fine finishes. This film-backed belt enables operators to quickly achieve desired Ra (roughness average) and other surface finish parameters. These are some of the reasons why this belt is used across industries, from metalworking to woodworking.
