This helps activate the peroxide for higher cure efficiency and faster vulcanization rates. NBR is actually a complex family of unsaturated synthetic rubber copolymers of acrylonitrile ACN oarts butadiene. Archived Nitrjle the original on 4 November As the Acrylonitrile increase the polymer will have greater oil and fuel resistance. Off-road equipment. Monomers are usually permitted to react for 5 to 12 hours. Nitrile rubber parts power can also be mixed into the raw compound to give lower friction and better abrasion resistance to final molded products. Find out why prints or CAD files can streamline the quoting process. It is commonly used to manufacture O-rings for automotive air-conditioning systems. An important factor in the properties of NBR is Nitrile rubber parts ratio of acrylonitrile groups to butadiene groups in the polymer backbone, referred to as the ACN content. Read the Blog. The Nitrile rubber parts is these compound have very short shelf life in the raw state.

It also is well known as Buna-N.

When is nitrile rubber the right choice for sealing and insulation? There are plenty of trade names for nitrile, too. No matter what you call it, nitrile rubber offers good resistance to oils, fuels, and chemicals. Elasto Proxy supplies specialty nitrile products to a variety of industries and can create a custom sealing solution that meets your specific requirements.

Nitrile rubber provides good-to-excellent resistance to many oils and solvents. Examples include:. Nitrile is also unsuitable for highly polar solvents such as acetone, which is used in some food processing and medical applications. Nitrile resists water, but provides poor resistance to weather, ozone, and aging. Through compounding, material suppliers have developed different types of nitrile with enhanced material properties. For example, hydrogenated nitrile butadiene rubber HNBR can withstand slightly higher temperatures than NBR and provides improved resistance to polar fluids.

Carboxylated nitrile butadiene rubber XNBR has a higher compression set than Buna-N and offers improved tear and abrasion resistance. Nitrile can also be blended with polymers such as polyvinyl chloride PVC. For engineers and buyers, choosing the right type of nitrile may involve comparing commercial rubber to specialty grades. Commercial grades generally cost less and are available in higher minimum order quantities MOQs.

Nitrile rubber products are used in the aerospace, defense, infrastructure, medical and health, and mobile equipment industries. Specific uses include:. Nitrile rubber is also used in appliance seals, medical gloves, and the bumpers for bowling alleys. Buna-N or NBR is supplied as sheets, rolls, and profiles. Nitrile seals and gaskets are usually made of solid sheets or extrusions, but closed cell Buna-N sponge rubber is used in applications that require a conformable gasket material. Water jet cutting supports fast, precise NBR gasket fabrication and eliminates the need to pay for or wait for tooling.

Hydrogenated Nitrile Rubber HNBR is the process of saturating the double bonds of the butadiene with hydrogen to give better resistance to oxidation and ozone. Phthalate type plasticizers are commonly used in compounding Nitrile Rubber. Typical ranges are between 14 to 50 percent acrylonitrile. Retrieved Metal oxide and fatty acid combination is used to accelerate the sulfur used to cure the NBR compound. Changing the levels of accelerators can improve compression set and speed the cure process so molded parts take less time in the mold.

The unique properties and higher temperature rating attributed to HNBR when compared to NBR has resulted in wide adoption of HNBR in automotive, industrial, and assorted, performance-demanding applications. On a volume basis, the automotive market is the largest consumer, using HNBR for a host of dynamic and static seals, hoses, and belts. HNBR has also been widely employed in industrial sealing for oil field exploration and processing, as well as rolls for steel and paper mills.

In this execution there are beside the sulfur bridges also carboxyl groups R-COO- on the double bond of the butadiene part. These ionic crosslinks are formed along with sulfur links.

Tire codes. Stearic Acid. Accelerator 1 to 3. Vulcanizing Agents 1 to 4. Polymer Polymer selection is based on application. This can help in dynamic application where a designer would not want excess compression from higher volume swell as the oil swells the rubber. Seal designers will then need to compensate for the larger volume swell that will be seen.

Speciality polymer can help improve compounds. These polymers will give improved tensile strength, tear, modulus and abrasion resistance. Application for these polymers are rollers, conveyor belts, hose covers, and down hole seals. The trade off is higher compression set, poor low temperature performance and less heat resistance. This improves ozone resistance for application that are exposed to environment but need oil and fuel resistance. Hydrogenated Nitrile Rubber HNBR is the process of saturating the double bonds of the butadiene with hydrogen to give better resistance to oxidation and ozone.

These polymers give superior physical properties, better resistance to ozone and oxidation, and have lower ACN version to give same low temperature performance.

Typically carbon black is used for many standard NBR compounds. Carbon Black is created from the combustion of oil or natural gas. The process is controlled to create various particle sizes which gives varying levels of reinforcing properties in a rubber compound. Lower particle N, N give higher level of reinforcement to the polymer, thus providing higher physical properties.

Trade off is typically give higher compression set for seal application. Larger particle N gives lower physical properties, but better compression set. Altering the different amount of carbon black will change the Shore Hardness or durometer of the final compound. White fillers can be used for compounds that need to be colored or in some cases improve the abrasion resistance of a compound like adding silica to a compound.

Some non-black fillers are calcium carbonate, clay, silica, talc and mica. Each one of these fillers have different level of reinforcements and like carbon black have different particle sizes and structure. Plasticizers are used to help the processability of the final compound. They also aid in the mixing of the compound to incorporate all the ingredients in the formulation.

Plasticizers can modify the physical properties of the final compound. Some changes in physical properties are lower hardness, improved flex and low temperature performance, changing swell tendency and flame or antistatic resistance. Plasticizers are often characterized by the polarity of the oil. Picking the correct polarity is important with NBR because higher ACN are higher polarity and can cause oils to bleed out.

Some families of plasticizers are aromatic esters, tricarboxylic esters, polymeric plasticizers, polyglycol diesters, and aromatic triesters. Phthalates are commonly used in NBR compound to give improved low temperature performance and where cost effective.

These types of phthalates are believed to extract easier and can cause reproductive issues. As an oil seal, there was not much concern. Many supplier now have moved away from using phthalates or switched to High Molecular Weight to prevent any issues with future regulations. Antioxidant are needed in NBR compound to prevent degradation of the unsaturated polymer backbone caused by high temperatures.
