1.Wear-resisting
2.Compressive

Silica gel circle is a kind of sealing. Silica gel is a rubber materials, because its performance heat-resistant wide, special chemical performance is excellent, reason and fluorine plastic together become special rubber. Silica is widely used in making various sealers, including silica gel laps, silica gel O RING, silicone set - etc.

Silica gel circle has excellent heat resistance, low temperature flexibility and special excellent resistance to oxidation and ozone performance, high permeability and the selectivity of gas through. Good electrical insulating performance (volume resistivity is more than 10 cm, breakdown voltage Europe. In extruded/mm above), bear the corona sex and resistance to arc sex. But add conductive carbon black, nickel powder, aluminum powder, silver, and can get appropriate conductivity (volume resistance to 5-0.02 Europe. Cm). Silica gel laps of low surface energy, has hygroscopic, isolation effect. Can rise Water resistant, but poor water vapor resistance, pressure exceeds more than 50psi are not recommended. And most of the oil, chemicals and solvent compatible. Acid-proof alkaline beautiful, general silicone rubber, not sufficient polar solvent resistance silane hydrogen and aromatic oil resistant. Don't recommend in most concentrated solvent, oil products, strong acid and diluted caustic soda solution. Special silicon rubber also are resistant to radiation, flame retardant, oil resistant properties. Its tensile strength low, resistance to wear, not normally used for weak dynamic seals.

Three temperature range - 60 °C ~ 225 °C, special silicon rubber high temperature can reach 300 °C, and low temperature to - 100 °C. (TR10 °C in - 100 down)

Four hardness limits A25 degrees above to 90 degrees.

Five color specified by the customer color.

All kinds of sealing ring role

V type sealing ring is a kind of axial role as the elastic rubber seal, without pressure seal shaft. Sealing lip good mobility and flexibility, can compensate larger tolerance and Angle deviation, can prevent internal oil or oil leakage outward, also can prevent external splash or dust invading.
Type O sealing ring is mainly used for static sealing and reciprocating motion seal. When rotating seal for turning sealing device and limited to low speed.
V type sealing ring general installation on a circle round or outside within for rectangular groove section of sealing function within.
