Low friction elastomeric compounds (slippery elas­tomeric compositions) are characterized by enhanced wear and abrasion resistance and ability to retain high performance under dry friction conditions. The selection of suitable contact materials is vital for submersible equip­ment for use in crude oil with high hard particle concentra­tions (of more than 500 mg/l).

Low friction elastomeric compounds have a dry friction coefficient against hardened steel of max 0,2 and are able to perform well even under dry friction conditions. This property makes low friction elastomeric compounds especially suitable for submersible oil and gas applica­tions such as marine bearings, thrust washers, PCP pump and down-hole motor stators (equipment life time is 400 days min).

To improve working efficiency of products in movable joints that are exposed to sliding friction against smooth metal surfaces is possible if one uses not only compound­ing (volume treatment) but surface finishing methods of already finished elastomeric materials as well.

Adsorptive-absorption treatment (AAT) method was devised and patented by REAM's experts. This method provides such increased product performance as follows:

-  low dry friction coefficient (static and dynamic) - 0,2 max;

-  ozone resistance;

-  no need for special lubricant for unit assembly;

-  contact temperature decrease of moving seal lips.
