China factory wholesale PU rubber O-Ring customized Silicone O Ring

O-rings are one of the most common seals used in machine design because they are inexpensive,

easy to make, reliable, and have simple mounting requirements, They can seal tens of megapascals

of pressure.

The O-ring may be used in static applications or in dynamic applications where there is relative motion

between the parts and the O-ring Dynamic examples include rotating pump shafts and hydraulic cylinder

pistons.

Silicone Rubber

Physically, silicones are based on silicon, an element derived from quartz. To create this class of synthetic

elastomers, pendant organic groups such as methyl, phenyl and vinyl are attached to silicon atoms. The

different additions of side chains can achieve significant variations in properties. Silicones have excellent

heat, ozone and corona resistance, are very well dielectric stability, and resistant to many oils, chemicals,

and solvents.
