Dongjiang Times reporter Liu Jianwei recently learned from Huizhou Li Changrong Rubber Co., Ltd. (hereinafter referred to as Huizhou Li Changrong Co., Ltd.) located in Daya Bay area that the company is investing funds to upgrade its technology and upgrade the quality of styrene-butadiene rubber products with hydrogenated solution. With the launch of the second phase project of Zhonghai Refining Oil Company, the company is striving to build Huizhou into one. The world's largest production base of solution styrene-butadiene rubber. At the same time, the R&D work of Taiwan base will gradually be transferred to Huizhou.

Li Changrong Group is Taiwan's largest solvent and rubber manufacturer and enjoys a high reputation in the world chemical industry. Huang Junjie, general manager of Huizhou Li Changrong Rubber Co., Ltd., introduced that in 2006, Li Changrong Group opened Huizhou Li Changrong Rubber Co., Ltd. in Daya Bay Petrochemical Zone, because there are two world-class petrochemical projects (China Sea Shell Project and China Sea Oil Refining Project).

According to reports, the company's main products include solution styrene-butadiene rubber and hydrogenated solution styrene-butadiene rubber, mainly used in plastic blending, such as wire and cable, automotive parts, soles, asphalt modification, adhesives and medical equipment. At present, the total assets of the company are 1.3 billion yuan, covering an area of 170,000 square meters. Li Changrong Group has three production bases of solution styrene-butadiene rubber in the United States, Taiwan and Huizhou, with a total annual output of 500,000 tons of solution styrene-butadiene rubber, accounting for 19% of the global market of similar products. Among them, Li Changrong of Huizhou accounts for 70% of the output value, reaching 350,000 tons.

"The choice to settle in Daya Bay before was to see the partition supply of China Sea Shell. The raw materials for our products, styrene and butadiene, are supplied by China Sea Shell, whose raw materials are the best. In the future, with the commissioning of the second phase of Zhonghai Refining Project, Li Changrong of Huizhou will become the largest solution styrene-butadiene rubber production base in the world, and the R&D of the base in Taiwan will gradually shift to Huizhou. Huang Junjie said that the company has recently upgraded its technology, upgraded the quality of its main styrene-butadiene rubber products with hydrogenated solution, actively developed medical grade composite materials, developed rubber raw materials for energy-saving green tires, and established a perfect technical service and research and development center (newly established hydrogenation catalyst laboratory and technical clothing experimental center).

It is reported that the hydrogenated solution styrene-butadiene rubber project of Huizhou Li Changrong Company has been put into trial operation at the end of June this year. The production is completed in two stages. The original plan is to produce 30,000 tons per year. It is expected to produce 35,000 tons per year in 2017. Recently, it is planned to expand production to 40,000 tons per year with an output value of $3,000 per ton. In terms of environmental protection, Huang Junjie said that the company regulated all parts of the possible impact on the environment within a control range, and all indicators met national standards. For example, the treatment of exhaust gas is carried out under the sealed condition of a pipeline, and its pollution is completely under control.

Hydrogenated solution styrene-butadiene rubber

Hydrogenated solution styrene-butadiene rubber (SEBS or SEPS) is the product of hydrogenation of primary styrene-butadiene rubber solution. It is odorless, non-toxic, white or transparent colloidal particles or powder, and its physical properties are quite stable. The colloidal particles and powders will not be deteriorated by ultraviolet irradiation under sunlight; they show high elasticity of rubber at room temperature and fluidity of plastics at high temperature. Compared with SBS (solution styrene-butadiene rubber), it has better stability and good heat resistance.

The main applications of SEBS include food and medical appliances, golf handles, food preservation boxes, and automotive parts. Jian Wei Liu
