It can be produced by free-radical emulsion polymerization of butadiene with 15 to 45 percent acylonitrile either hot (hot rubber) or cold (cold rubber): NBR grades with high acrylonitrile content have better oil and abrasion resistance, whereas grades with low acrylonitrile content have better low temperature flexibility and resilience. Technical Data Sheet: Nitrile Rubber. Nitrile should not be used in highly polar solvents such as acetone and MEK ozone chlorinated hydrocarbons and nitro hydrocarbons. NBR can be used for production of rod seals, piston seals, non-standard seals (special seals) and other components. No vendors are listed for this material.

Material Data Sheet. in sealing technologies, where «soft seal» is required, but NBR has a lower hardness than TPU, thus sealing out of this material have a lower resistance to extrusion with the same design. NBR materials are one of the most commonly used elastomers in sealing applications. TECHNICAL DATASHEET NBR/PVC rubber sheet Protects against condensation Pronat Industries LtdNBR/PVC Tzavei Hanachal St. Emek Hefer Industrial Park Emek Hefer Israel 38777 Tel. NBR is mainly used in cases, where high fuel and mineral oil resistance, high elasticity and low residual strain are required, i.e. Seals out of NBR, compared with seals of the TPU, allow a short "run dry" and can work in a more abrasive work environments, such as in high dust content in cement production. NITRIL RUBBER (NBR) ARJUN K GOPI 2ND M.Sc BPS 2. Receive regular email updates from Alpana products. Nitrile Rubber (NBR, Acrylonitrile-Butadiene Rubber) Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE) Material Notes: Nitrile Rubbers are copolymers of butadiene and acrylonitrile. Utilization, application and processing of the products befall completely outside of our control and are therefore solely your liability. Please. The process of ageing starts in the atmosphere at 80°C, the ageing considerably slows down when reducing the inflow of hot air (for example, in hot oil). NBR is not resistant to glycol based break fluids, to aromatic hydrocarbons (for example, toluene, … Material datasheet Rubber compound | NBR For more information, quotations or orders concerning this material please visit www.eriks.info. Certainly, we do assure the immaculate quality of our products in concordance with our general sales and delivery conditions. The service requires full cookie support in order to view this website. Acrylonitrile content may range from 18-50%. NITRIL RUBBER (NBR) 1. This elastomer has low ozone, weather and ageing resistance. NBR is generally damaged by ozone, chlorinated solvents, ketones, aldehydes, esters, and nitrogen-containing solvents. This is due to Nitrile's compatibility with most environments as well as it's relative cost compared to other rubber materials. : +972 4 628 6888 Fax: +972 4 628 6890 www.pronatindustries.com www.pronatmedical.com sales@pronatindustries.com Material Discription. Chlorinated hydrocarbones (trichloroethylene), Fire-resistant pneumatic fluids HFA, HFB, HFC, Silicone oil and grease (oils can cause the decrease). Mykin’s RN00170, Nitrile (BUNA-N) 70 durometer, is a general purpose copolymer of butadiene and acrylonitrile. © 2014 – 2019 Alpana d.o.o. Linagard® NBR also exhibits excellent high temperature service and can be used up to 110°C (230°F) with suitable adhesives, or where mechanical fixing is employed.

NBR possess high hardness and for rubber elastomer has a very high resistance to abrasion (90mm³). weir-iglusjax.stackpathdns.com is using a security service for protection against online attacks. Trade names include Perbunan, Nipol, Krynac and Europrene.This rubber is unusual in being resistant to oil, fuel, and other chemicals. NBR offers excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols. It is resistant to oil, fuel and other chemicals (the more nitrile within the polymer, the higher the … weir-iglusjax.stackpathdns.com is using a security service for protection against online attacks. 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. Acrylonitrile butadiene rubber (NBR), usually shortened to nitrile, is a unique elastomer. error. It is the most widely used and economical elastomer. NBR is an elastomer based on acrylonitrile-butadiene rubber. General Notes: Nitrile is a general purpose oil resistant polymer which has good solvent, oil, water and hydraulic fluid resistance, good compression set, abrasion resistance and tensile strength.
