Buna material

Trade names include Perbunan, Nipol, Krynac and Europrene. The most widely used 0-Ring elastomer. Excellent resistance to petroleum products. Buna S The material was initially marketed with the brand name Buna S. Its name derives Bu for butadiene and Na for sodium (natrium in several languages including Latin, German, and Dutch), and S for styrene. Buna is a widely used elastomeric material known for its tensile strength and high fuel and oil resistant properties.

It combines resistance with low compression set and high abrasion resistance to make it the seal industry’s most widely used economical elastomer. In stock and ready to ship. Both Buna and Viton rubber are specifically designed to resist nearly any oil and provide excellent compression set resistance. Either will work in a moderate temperature application, such as industry and manufacturing. What does Buna rubber mean?

Buna -N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Viton and Buna are two of the most commonly used elastomers for sealing applications and for good reason. Both of these rubbers serve as great general purpose sealing options. These seals offer excellent compression set resistance, and both options are designed to resist most oils and lubricants, especially petroleum based lubricants.

Some of the common types of O-ring materials include PTFE , Nitrile (Buna ), Neoprene , EPDM Rubber and Fluorocarbon (Viton ). The basic monomers are butadiene and styrene, with styrene content approximately 23. In this article, Martin’s Rubber Company explains more about the properties, applications, pros and cons of this versatile rubber material. Nitrile, often referred to as Buna -N or NBR, serves as an ideal rubber gasket material for applications involving oils and solvents.

Material Reference. Rubber compounding is a very broad and technical fiel since basic rubbers or elastomers are mixed with various chemicals and ingredients (and even with each other) to obtain desired physical properties. Nitrile rubber, also called nitrile-butadiene rubber (NBR, Buna -N), is a synthetic rubber that provides excellent resistance to petroleum-based oils as well as mineral and vegetable oil. Timco Rubber can work with your business to design and provide nitrile parts customized for the specific needs of your applications.

O-ring material family chemical compatibility, temperature resistance, and other properties all factor in to o-ring material selection for an application. Chemical Compatibility Guide for Nitrile ( Buna N) 3. This popular o-ring material family comparison shows basic rubber material family properties and performance plastic properties. Buna -N tank gaskets are comprised of a synthetic rubber copolymer and are very well suited to storage of crude oil and other petrochemicals.

When storing ketones, esters and aldehydes in steel tanks, other gasket material is recommended for better longevity. It has good elongation properties, as well as adequate resilience, tensile and compression set. Farlex clipart collection. BUNA -N, NITRILE, NBR, HYCAR, PARACRIL are all the same material. Butadiene (which provides the resilience properties of rubber) and acrylonitrile (which provides the oil resistance property).

Buna -N Rubber Grommets result found that include products Protect and cover through holes on machinery and equipment with a selection of rubber grommets from Grainger. They can be used to hide and protect wires, minimize vibration, cover sharp edges and prevent abrasion of the material that they are mounted on. It is synthetic rubber copolymer of acrylonitrile(ACN) and butadiene. Elastomer is natural or synthetic material which does not break when stretched and when released it return to its original length.

NBR material features superior levels of resistance to synthetic and natural oils and greases. Buna-N is a commonly used elastomer. It also possesses good resistance to abrasion.

It is normally the least expensive of the rubber types we will discuss here. NBR is compatible with petroleum fluids (including dinosaur and synthetic lubricating oils, pure gasoline, and diesel fuel).
