Hydraulic O-rings of different materials in different scope

 

Press hydraulic O-ring different scope of application, there are different requirements, the above formula can do Cot. Lining transition used, the excess sulfur can penetrate into the surface of the plastic go, curing time can be vulcanized rubber roller can be controlled. If you do the battery shell, clarinet accessories, and other man-made jade, it is necessary for a long time a secondary vulcanization.

 

If the seal ring work environment only come into contact with oil, choose (NBR) NBR rubber material can be. Division I professional production and sales of hydraulic oil nitrile O-ring, full size, stock, quality assurance. NBR is mainly oil, wear-resistant, long-term use of high temperature does not exceed 100 degrees, if it is exposed to chemical substances, recommended to choose (VITON) fluorine rubber, fluorine rubber than NBR but the price much higher. Fluorine rubber mainly chemical resistance, acid, oil, wear-resistant, long-term use of high temperature does not exceed 220 degrees.

 

The auxiliary hydraulic O-rings using the following:

 

? Hydraulic O-rings Nitrile rubber (NBR)

 

Suitable for temperatures below 90 ? of water at room temperature;

 

? Hydraulic O-ring Viton FPM (domestic)

 

Apply to water at room temperature and low temperature heat transfer oil 150 ? or less;

 

? Hydraulic O-ring Viton FPM (import Kai Ming)

 

HTF 195 ? apply to the following;

 

? Hydraulic O-ring perfluoroether FFKM (DuPont, Shanghai Jia Jing)

 

HTF applies to below 250 ?;

 

? Hydraulic O-ring of ethylene-propylene rubber (EPDM)

 

Suitable for hot water below 150 ? of superheated steam;
