Elastomers are lightweight and flexible. They also retain their original properties in extremely hot and cold environments, making them popular in demanding automotive and appliance assembly applications.

Typically, manufacturers use FKM elastomers coated with conventional lubricating waxes to reduce the excessive friction these applications can produce, but the high processing temperatures volatize the waxes. A second approach is to coat the elastomer with molybdenum disulfide, graphite, silicone oil, or PTFE powder. However, these coatings easily wash off the surface, and the elastomers are again subject to wear, and ultimately, premature failure.

In a rotary sealing application, an F-Treated Quad Ring seal has permanent low coefficient of the friction surface, improving system performance.

F-Treat, a process developed by Minnesota Rubber and Plastics, permanently modifies the chemical structure of the entire elastomer. It has minimal effect upon its original or aged properties, it is effective with any FKM fluoroelastomer, and it will not dissipate with wear. Further, it does not affect the FDA approval of appropriate compounds.
