In pneumatic and many hydraulic applications, seal friction can negatively affect system performance.  UltraMod™ was developed especially for fluorocarbon (FKM) rubber polymers to address their high coefficients of friction.

While PolyMod^® polymer modified FKM elastomers have low friction and improved wear life, UltraMod™ high performance FKM elastomers are polymer modified to have the ultimate low coefficients of friction and optimized wear life giving them significant advantages over conventional elastomer seal materials.

UltraMod™ is similar to our PolyMod^® process and provides the same benefits without adversely affecting the basic engineered properties of the FKM material.  

UltraMod™ is the ultimate in coefficient of friction reduction for FKM materials.

 Performance is improved using UltraMod™ materials. This has been demonstrated in both controlled tests and actual service applications (see Application Highlights).

UltraMod™ FKM seal materials have:

• Reduced Friction
• Reduced Abrasive Wear
• Increased Wear Life
• Improved Performance
• Lower Heat Buildup
• Consistent Performance 

Unlike other friction reduction methods, such as coatings, impregnations, and internal lubes, 

UltraMod™

• Is permanent
• Lasts the Seal’s Lifetime
• Does Not Add Impurities
  • Safe for Medical and Food Applications
  • No System Contamination
• Does Not Adversely Modify Material Properties
• Does Not Dimensionally Change a Seal

UltraMod™ high performance FKM materials have significantly less friction than conventional FKM elastomers.

Evaluations using ASTM D1894Results were obtained with test specimens made from the same FKM compound and batch for all three sets. One set was left unmodified as the control (Standard); one was PolyMod processed (PolyMod®) and the third was UltraMod processed (UltraMod™).
