NBR rubber nitrile butadiene rubber, usually abbreviated to nitrile, is a unique elastomer. It can be produced by polymerizing a free butadiene radical emulsion with 15 to 45% Warm acilonitrile (Warm rubber) or cold (cold rubber). China and Taiwan are among the largest NBR manufacturers.<\/p>\n
NBR grades with high acrylonitrile content have better oil and abrasion resistance, while grades with low acrylonitrile content have more flexibility and better flexibility at low temperatures. In general, nitrile tires have only moderate physical properties but good abrasion and excellent resistance to oil and hydrocarbon solvents.<\/p>\n
Many properties can be adjusted by changing the amount of acrylonitrile in nitrile rubber. The higher the nitrile content, the higher the hydrocarbon resistance and the lower the nitrile content, the better the low temperature flexibility.<\/p>\n
Nitrile butadiene is used in NBRs where high oil resistance is required. They are widely used in sealing, especially for oils and gasoline (aliphatic hydrocarbons).<\/p>\n
Major applications of NBR include gaskets, seals, diaphragms, gasoline hoses, liners, tubes, rings, and cable sheaths. Carboxyl grades are also used in many epoxy formulations as rubber hardeners.<\/p>\n
Normal degrees have a working temperature range of -25 to 100 degrees Celsius. Some low acrylonitrile materials are suitable for use up to -50 \u00b0 C and some curing peroxide grades increase to + 150 \u00b0 C.<\/p>\n
Based on acrylonitrile monomer percentage, NBR is divided into the following grades and grades:<\/p>\n
The NBR family of nitrile butadiene rubber also includes special grades with high performance. These grades include isoprene-containing types (Acrylonitrile-Butadiene-Isoprene Rubber (NBIR)), Carboxylated Nitrile Rubber (XNBR), and powder and liquid NBR types.<\/p>\n
