Conventional oil seal type&materials
Buqing rubber (Code NBR)
[Operating temperature]:30-100 degrees Celsius
[Main features]: oil resistance, heat resistance, good wear resistance. Widely used in the production of sealing products, but not suitable for phosphoric acid series hydraulic oil and gear oil containing extreme additives.
Silicone material (code PMQ or VMQ)
[working temperature]:60-200 degrees Celsius Main features: good heat resistance, cold resistance, small compression permanent deformation, but low mechanical strength.
Fluorine glue (code FKM)
[working temperature]:20-200 degrees Celsius
[Main features]: Heat resistance, acid and alkali resistance and other chemicals: oil resistance (including phosphoric acid vinegar series hydraulic oil)
Suitable for all lubricating oil, gasoline, hydraulic oil, synthetic oil
EPDM (code EPDM or EPM)
[operating temperature]:50-150 degrees Celsius [Main features]: good weather resistance, aging resistance in the air, oil resistance in general, can be resistant to freon and a variety of refrigerants.
Polytetrafluoroethylene (code PTFE)
[Working temperature]:200-260 degrees Celsius [Main features]: good chemical stability, good heat resistance, cold resistance, oil, water, steam, chemicals and other media: high mechanical strength, high pressure resistance, good wear resistance, low friction coefficient, good self-lubrication. Polyurethane (code PU)
[Operating temperature]:35-100 degrees Celsius
[Main features]: Good mechanical properties, excellent wear resistance and oil resistance, but the working temperature is not
High.
