Nbr 70 material

Nitrile metric o-rings o-rings are widely used in the seal industry. They can also be compounded for service over a temperature range of -40°C to 135°C. NBR (Nitrile), chemically, is a copolymer of butadiene and acrylonitrile. Acrylonitrile content varies in commercial products from to. As the NBR content increases, resistance to petroleum base oils and hydrocarbon fuels increases, but low temperature flexibility decreases.

It is the most widely used and economical elastomer. NBR offers excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols. Make sure you review all of our other popular materials to make sure that the material you choose is correct for your application. If you need properties that are slightly different than the ones listed below, we can compound the formulation of the rubber material. NBR Shore A - NBR - Nitrile rubber (oil resistant, for normalized sealing mechanics) 0-rings, also known as rubber rings and sealing rings are the most frequently used type of seal.

It is due to the fact that installation of 0-rings is very easy and that they require little space. If the selected material the design. DMR NBR is a black Nitrile Butadiene Rubber, commonly referred to as NBR , Nitrile or Buna. Good physical properties and chemical resistance to Good physical properties and chemical resistance to the most common hydraulic fluids makes NBR an excellent sealing material. O-Rings: Typical lead time for out of stock o-rings is 1-weeks from time of order.

This can vary based on manufacturing scheduling, material type, or size. This sealing ring is black with a yellow spot and made from nitrile rubber and is the sealing ring to be used where there are petrol or oil residues on the waste water (e.g. in connection with oil and petrol separators at service stations, garages etc.). Nitrile rubber, also known as NBR , Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene.

Trade names include Perbunan , Nipol , Krynac and Europrene. O-Rings and rubber parts accurately manufactured using quality raw materials. Continuous research for solutions and technologies to obtain better products and a long-term perfect sealing. Examples of applications and industries where nitrile ( NBR , buna-N) is used include: Automotive Industry Nitrile, also known as buna-N, has oil resistant properties that make it the perfect under-hood material.

The acrylonitrile content of nitrile sealing compounds varies considerably ( to ) and influences the physical properties of the finished material. The higher the acrylonitrile content, the better the resistance to oil and fuel. At the same time, elasticity and resistance to compression set is.

Nitrile butadiene rubber ( NBR ) is a family of synthetic rubber copolymers of acrylonitrile and butadiene. Although its physical and chemical properties vary depending on the polymer’s composition of nitrile, this rubber types are generally resistant to oil, fuel, and other chemicals. Rubber Moulding Materials for injection, compression and transfer moulding. UK based specialist manufacturers of Rubber and Silicone Mouldings.

It is suitable for high vacuum applications. Many fluorocarbon compounds have a higher than normal mold shrinkage rate, molds for fluorocarbon products are often different from molds for Nitrile. Free Delivery on Eligible Orders! Physical properties required actual Density 1. In this article, Martin’s Rubber Company explains more about the properties , applications, pros and cons of this versatile rubber material.

Nitrile is the most cost effective and commonly available O-ring material. Ideal for use as seals for pumps, drive belts, and other general engineering applications in the hydraulic and pneumatic industry. NBR is good for applications where the O-ring is. Materials : Nitrile rubber ( NBR ) Good resistance to : Mineral oils and greases, hydraulic fluids (petro based), aliphatic hydrocarbons, alcohols, glycols, LPG and natural gas, diesel fuel, fuel oil, animal and vegetable oils, hot water up to 90°C. For higher temperatures and chemical exposures, standard quality Viton FPM Sh can be used.

Material hardness is given on the “Shore” or “IRHD” scales. Please inquire for non-standard materials such as. Vendors: No vendors are listed for this material.
