In April, SINOPEC Yanshan Petrochemical Synthetic Rubber Factory successfully realized mass production of low-cis polybutadiene rubber, in which two key indexes, gel content and halogen content, were better than those of similar products imported.


At the beginning of April, after receiving the order from the client, requesting mass production of low-cis rubber, SINOPEC Yanshan Petrochemical timely cooperated with Yanshan Branch, Beijing Research Institute of Chemical Industry to jointly develop low-cis rubber products conforming to the demands according to the product index requirements. After professional test and analysis, the chroma index of the products was controlled stable, in which, the gel content was stably controlled below 150ppm and the halogen content is controlled below 50ppm, these two key indexes were better than those of similar products imported.

SINOPEC Yanshan Petrochemical Synthetic Rubber Factory can switch to produce the products of various brands and customize the rubber brand according to the customer demand. Compared with high-cis rubber, low-cis rubber possesses the advantages such as low gel content, good solution chroma, no transition metal and moderate rubber particle size. Because of high control requirements of production process, it belongs to refined product among synthetic rubber products. At present, the high-end low-cis rubber used in China mainly depends on import.
