H-NBR

Hydrogenated NBR

“Zhanber^®” is a highly functional synthetic rubber obtained by hydrogenating NBR with “Zhan Catalysts,” which Zannan SciTech Co. Ltd has developed independently.
The company offers ten kinds of regular grades and seven kinds of special grades.
The product can also have its degree of hydrogenation and its amount of Acrylonitrile (AN) adjusted to meet the customer’s needs, enabling to produce the customer’s desired H-NBR.

Manufacturer introduction

Zannan SciTech Co. Ltd. was founded in 2009, placing its head office in Minhang industrial region, Shanghai, China.
The company produces Zhanber^® H-NBR using Zhan catalysts, which the company has developed independently, at the factory having site area of over 40,000 square meters, placed in Zhejiang Province, China.
President Zhan, who has developed the Zhan catalyst, owns more than 30 patents inside and outside China and has accomplished over 20 innovative research projects in China, and therefore has been highly appreciated by the Shanghai Municipal government.

Main applications

H-NBR is widely used in the fields of automobiles, oil field development, and aerospace. It has excellent oil resistance, corrosion resistance, acid resistance, ozone resistance, dynamic fatigue resistance, heat resistance, and cold resistance, and also has excellent mechanical properties such as tensile strength.
