INTERNALLY LUBRICATED COMPOUNDS

For those applications where an external lubricant like RT Dygert’s Seal Kote™ or Seal Lube™ is not desirable (such as automatic feeder bowl assemblies), RTD Dygert offers the internally lubricated compounds in the table below. Internal lubrication involves the introduction of a lubricating agent into the compound during the mixing stage. The advantage of this type of lubrication is that the lubricant is dispersed throughout the compound, and therefore the cured part, instead of just on the surface.  Since all rubber compounds have relatively high coefficients of friction (COF), it is very important to counteract this in the most efficient way possible, especially in dynamic sealing applications.

Different internal lubricants have different effectiveness in reducing the COF, but RTD’s proprietary organic lubricant is by far the most effective. Due to its chemical makeup, it is best suited for compounds where the curing temperature is not too high, such as nitriles and EPDMs.  It should be noted, however, that some fluids and solvents can dissolve or leach out our proprietary lubricant, so testing in the actual environment is always recommended.

For two of our most popular internally lubricated compounds, N-7010 and N-7044, a coefficient of friction test report and a case study can be obtained by contacting customer service. Unless otherwise specified, all our internally lubricated compounds are black in color.
