Rulon® is one of the materials that we are asked about most often. While there are over 300 unique formulas of this material, today we’ll review some of the most-common formulas. No matter which formula your application requires, you should expect a versatile, self-lubricating, and low-friction material for bearings, seals, gaskets and structural components.
There are literally hundreds of variations of Rulon, but in our experience, the most popular are Rulon® 641, Rulon® J, and Rulon® LR. Each offers slightly different attributes, yet all have delivered superior results to our clients.
For more details and technical specs on the materials below, our Rulon Comparison Chart is a great resource!
