Since 2006, Focus on rubber seals

Nitrile the performance characteristics of the rubber sealing ring (o-ring)

by:ORK      2020-07-28
Nitrile rubber is more common in type O rubber seals sealing ring, is often used as a hydraulic seal, pneumatic systems, NBR as O rubber seal commonly used material, its main performance characteristics? Oil resistance: NBR O rubber sealing ring has the very good oil resistance, oil resistance of its behind thiokol and fluorine rubber, and has very good abrasion resistance and air tightness; Its shortcoming is not resistant to ozone, halogenated hydrocarbon, ketone and aromatic compounds and esters solvent, is not suitable for insulation. Heat resistance, heat resistance of NBR is better than that of styrene butadiene rubber, neoprene, can work under 120 ℃ high temperature, air tightness after butyl rubber. NBR will suffer the effect of acrylonitrile content, the performance of the acrylonitrile content, the tensile strength of the nitrile rubber, heat resistance, oil resistance, air tightness, hardness increased, but the flexibility, lower cold resistance. Purpose: NBR O rubber sealing ring is used mainly for oil products, such as tubing, adhesive tape, rubber seals diaphragm and large oil capsule, etc. , are often used to produce all kinds of oil resistant moulded products, oil seal, cup, diaphragm valve, corrugated pipe, rubber hose, seals, foam and so on, also used to make plastic board and wear-resistant parts. NBR O rubber sealing ring is not to say that the material is nitrile rubber, is the main material is nitrile rubber, because every client need various properties such as wear resistance, hardness, heat resistance of the different, so at the time of mixing tend to be based on a variety of formulations to allocate refining, thus to get the final materials. So when purchasing needs like O working condition of rubber sealing ring manufacturer instructions, to produce the appropriate sealing ring, sealing of 17 years guangdong seal manufacturers, professional custom fit for the customer the hydraulic seals, if there are any materials or other aspects of doubt, welcome your consultation.
