※ excellent sealing performance of sealing ring, high working life, the working life of dynamic pressure sealing is 5-10 times higher than that of conventional rubber sealing products, up to dozens of times, can be the same as the life of sealing base under certain conditions.

※ sealing ring friction resistance is small, the dynamic and static friction force is the same, is "0" rubber ring friction 1/2 -- 1/4, can eliminate the low speed, low pressure movement "crawling" phenomenon.

High wear-resistant sealing ring, sealing surface wear with automatic elastic compensation function.

Excellent self-lubricating performance of sealing ring. Can be used for oil-free lubrication seal.

The sealing ring has simple structure and convenient installation.

※ working pressure of sealing ring: 0 to 300MPa; Working speed: ≤15m/s; Operating temperature: -55 -- 250℃.

Applicable media: hydraulic oil, gas, water, mud, crude oil, emulsion, water-glycol, acid, alkali, chemicals, etc.

The performance of silica gel is very stable, at the same time resistant to climate aging, resistant to non-combustible hydraulic oil, water, high-pressure steam and chemicals of phosphate ester system. So it's perfectly safe.

In addition to the general requirements of sealing ring materials, the sealing ring shall have the following characteristics:

(1) elastic and resilient;

(2) appropriate mechanical strength, including expansion strength, elongation and tear strength, etc.

(3) stable performance, not easy to swell in the medium, small thermal shrinkage effect (joule effect).

(4) easy to process and shape, and can maintain precise size.

(5) no corrosion of contact surface, no pollution of medium, etc.
