Good elasticity and compression set properties, it is rubber o-rings, rubber seals, rubber seal products rely on a magic weapon, only in this way can meet the sealing conditions of various kinds of mechanical equipment.However, due to mechanical equipment and the sealing medium is different, have different requirements rubber have performance properties.
As a dynamic seal, insist on rubber with good medium resistance, abrasion resistance, tear resistance and heat resistance performance, also have low compression deformation and the tensile strength of;As a static seal, insist on rubber with good oil resistance and compression set resistance;Seal for high vacuum system, insist on rubber airtight and not easy volatile, requires both high temperature aging, and at low temperature can maintain a degree of elasticity;Seals used in different medium, insist on rubber volume and the hardness change in the medium to small, other performance to reduce the amplitude is smaller, and should not be metal rubber surface corrosion effects.
