O-shaped sealing ring rubber formulation design.

O-shaped rubber seals work in a variety of complex environments, it requires its rubber has some special properties. In the hydraulic system, the requirements of good oil resistance, temperature resistance, low compression permanent deformation and a certain tensile strength. As a dynamic seal, in addition to the requirements, the compound should have good abrasion resistance and tear resistance. Used for special media sealing is required in the medium of the volume change and hardness change is small. In short, the formula design should be based on specific working conditions, media type, temperature, working pressure and application status and other comprehensive consideration.
