3M Brushlon roll 320B features short trim nylon bristles resist loading and chemical wear. These short trim bristles are especially helpful when used for noise reduction on workpieces, moving parts and creating non-slip surfaces. Brushlon products come in many variations - so, how do you know which one is right for you. Through a combination of three variables: bristle type, mineral and converted form. 3M Brushlon roll 320B can be cut and shaped to meet project dimensions and its short trim nylon fibers provide a clean finish with the aggressive cut of a mineral infused brush. 320B does not contain mineral and while this may seem surprising for an abrasive product - the omission was intentional. The absence of mineral leverages the abrasive's ability to respond to parts without gouging or marring. Abrasive bristles on 3M Brushlon 320B counteract common pitfalls of tufted brushes. In tufted brushes, multiple bristles are attached with only a single fiber. If it breaks, multiple bristles are lost, which causes gapping and limits use. But, with non-tufted Brushlon materials, each bristle is individually anchored to a tough resin fiber backing, minimizing bristle loss and maximizing brush life. Backed by more than 30 years of experience in brush development, the 3M Brushlon line offers you multiple options: nylon or polypropylene bristles, wide range of fiber diameters, many brush sizes and configurations and minerals. The durable resin backing also enables the abrasive to be run wet or dry. Regardless of the 3M Brushlon product that's chosen, industrial professionals can anticipate a uniform benefit: great performance part after part.
