The 3M Trizact™ 272 LA abrasive belt has been specially developed for use on belt sanders. This belt is used for fine grinding, as well as polishing edges and surfaces on glass and glass-like materials.
In contrast to conventional grinding belts, the grinding pattern is always the same colour. When the abrasive on the film backing is exhausted, the belt changes colour.
The required contact pressure is lower than with conventional grinding belts; the abrasive allows for three times longer service life than conventional grinding belts.
About the product series 3M™ Trizact™:
Microreplication of pyramid-shaped particles for long tool life:
Trizact™ structured abrasives are based on a precisely arranged, three-dimensional structure of tiny mineral particles. As they are worked off, new layers of abrasive particles are continuously exposed - right down to the backing. Even when the belt is half ground, over 85 % of the abrasive particles are still available. The result is a service life many times longer than that of conventional abrasives.
Application note:
Recommended speed: 11-14 m/s
