Acrylonitrile content, Mooney viscosity and Iodine value of HNBR
What is HNBR?
HNBR is a highly saturated elastomer that is treated by catalytic hydrogenation of nitrile rubber (NBR).
How about Dawn HNBR?
Dawn Special Elastomer Co., Ltd. is an enterprise that develops, produces, and sells HNBR products with high technology content and high added value, and at the same time extends the processing and production of mixed rubber downstream.
The HNBR plant has a designed capacity of 3,000 tons per year, and the first phase of 1,000 tons was officially produced in 2019. The HNBR produced by Dawn Special Elastomer Co., Ltd makes China the third country in the world to break through HNBR technology in industrialization besides Germany and Japan.
