1) kaboksil NBR (XNBR)
Introduction of carboxyl modification into NBR can significantly improve the wear resistance, adhesion and aging resistance of NBR [3]. The product is mainly used to prepare rubber products, adhesives and mechanical parts with higher requirements on strength, oil resistance and wear resistance [4]. It is widely used in aerospace, equipment manufacturing and other fields, and is a special high-performance NBR.

2) NBR (HNBR) i haidrojen.
Hydrogenated NBR (HNBR), also known as high saturated NBR, partially or completely hydrogenates the unsaturated double bond on the NBR carbon chain. There are three main preparation methods: hydrogenation of NBR solution, hydrogenation of NBR emulsion and copolymerization of ethylene and acrylonitrile [5].Its main manufacturers are lanxen company (10,000 tons/year) and ruiong chemical company (12,000 tons/year), the world total production capacity of 22,000 tons/year, is the largest amount of special rubber varieties.It is mainly used in the fields of automobile oil seal, fuel system parts, automobile transmission belt, piston for drilling and holding box and mud, rubber rola bilong printim na tekstil, laina bilong tenk belt, pasim ol hap bilong aerospace, ol samting bilong pasim ea kondisen, ol samting bilong daunim hevi, na ol narapela samting bilong.

It is expected to achieve technological breakthroughs in the industrialization of HNBR in 2015.At the same time, some progress has been made in the prosesim teknoloji, we i putim as bilong promotim moa na yusim petrochina HNBR.
3) butadien - akrilonitriel - isren raba (NIBR)
Isoprene modified NBR technology (NIBR) is a kind of NBR with high strength, high elasticity, easy to process, is a special high-performance NBR.Mainly used in printing, aerospace and other fields [8].The key points are the sequence structure control of isoprene in copolymerization or grafting reaction, the viscosity control of nitrile na Mooney, na teknoloji bilong kodinesen bilong prosesim .
