Nitrile rubber O-rings often referred to as Buna-N oring seals&NBR O-rings
The most commonly used elastomer in the seals industry and is a copolymer of two monomers; acrylonitrile (ACN) and butadiene.
The properties of this elastomer are ruled by the ACN content which is broken down into three classifications:
? High Nitrile: >45% ACN content
? Medium Nitrile: 30 – 45% ACN content
? Low Nitrile: <30% ACN content
It is the best rubber material with oil resistance, usually used to make sealing rings, oil seals, gasket,washer and is widely used in various sealing industries.■.Properties of NBR Buna-N (Nitrile &Buna-N) Rubber:
Hardness, Shore A:50 - 90
Tensile strength:500- 2500 PSI
Elongation at break %:600% maximum
Density:Can becompounded around 1.0g/cm3■.NBR O-ringsTemperature Range:
Standard Low Temperature:-25℃(-13℉)
Standard High Temperature: -120℃(248℉)
※The temperature range is the reference value of the typical compounds, the value is different according to the material formulation, please consult the
LanHe Seals engineering and technology Department for details
■.NBR O-rings Cure system:
1.Sulfur-Cured
Standard Nitrile o-rings are usually sulfur-cured.Sulfur-cured compounds
offer better low-temperature properties but are more prone to hardening
with high temperatures.2. Peroxide-Cured
Peroxide-cured nitrile o-rings have better heat resistance and lower compression
sets but are more expensive and more difficult to process.■.NBR O-rings Hardness range:70~ 90 Shore A (N70&N80 &N90)
※The most widely used and most in stock in LanHe Seals is the standard hardness of 70 Shore A■.Molecular formula of NBR rubber material:
■.NBR O-rings advantage：
1. Durability
Nitrile rubber is highly durable and can withstand harsh environmental conditions, including exposure to chemicals and oils. Its ability to resist wear and tear makes it suitable for use in applications that require long-term performance.2. Oil and Fuel Resistance
Nitrile rubber is highly resistant to oils and fuels, making it an ideal choice for applications in the automotive,oil and gas, and manufacturing industries. Its resistance to these substances ensures that it can provide reliable performance even in environments with high exposure to oils and fuels3.Cost-Effectiveness
Nitrile rubber is a cost-effective material that offers numerous benefits and can provide efficient solutions for various industrial applications. Its versatility and durability make it a popular choice for manufacturers looking for cost-effective solutions without compromising on quality.■.NBR O-rings dimensions：
CODE1: CS--Cross Section
CODE2: ID--Inside Diameter
CODE3: OD--Outside Diameter OD=ID+CS*2 Length = (ID + CS) * π
