The most important component of an oil seal is the material.

To consider the environmental conditions, the following properties

are important:

 Good chemical resistance

 Good resistance to heat and low temperature

 Good resistance to ozone and weather aging

 Good elasticity

 High resistance to water

 Low compression set

 Raw material cost

In order to satisfy various sealing conditions, COS has many compounds

available for your choice.
