Strong acid ion exchange resin is a kind of granular product with sulfonic group on the crosslinked styrene skeleton. It can be used in all pH ranges (0-14), stable at various temperatures and resistant to high temperatures of 100-120℃. Therefore, it is widely used in water treatment for manufacturing pure water and soft water, as well as in pharmaceutical products, food refining, catalyst and other fields.

Sunresin has developed a series of special resins for water treatment that exceed the standard. It can specifically and accurately remove the excessive boron, fluorine, nitrate and chlorate in the water source, so as to achieve the continuous compliance with water quality standards.

In the first half of 2020, Sunresin took active measures to minimize the impact of the epidemic. In terms of production, the new production capacity has been released obviously with the construction completion of the new production base, and the production capacity bottleneck which has restricted the development of the company for many years has been broken. As for R&D, the R&D for key application fields and urgently needed resin varieties in the market has been rapidly enlarged, and remarkable results have been achieved. In terms of sales, the large application fields for the international market started steadily, showing a good development momentum; Besides, Sunresin has strengthened the marketing organization in key areas of the domestic market and has been looking for new growth opportunities. In the aspect of system engineering project, as we all know, the personnel flow is limited strictly because of the 2019-nCoV, so it is impossible to provide on-site commissioning service, the customers also couldn't visit China.

Seplite® CT104 etherification system deacidification agent has the performance advantages of strong contamination resistance, high number of strong base functional groups, and synergistic effect by introducing complex groups, which can effectively remove acidic ions, metal ions, chloride ions and other impurity ions from etherification system circulating water.

Sunresin has developed resin products and application process suitable for anthocyanin extraction from different raw materials, which can meet the purification of anthocyanin extracted from different raw materials. For example, anthocyanins from berry and floral plant sources can be used with Sunresin Seplite® LXA-86 macroporous adsorbent resin. For anthocyanins from vegetable plants, Sunresin Seplite® LXA-868M macroporous adsorbent resins can be used, which have large adsorption capacity and greatly improve the content and solubility of finished products, thereby facilitating the development of back-end applications.

Sunresin has developed a series of chelating resins and ion exchange resins to efficiently and accurately treat the water quality that exceeds the standard based on the continuous efforts of R&D team. These resins can be used to realize highly selective and accurate adsorption and removal of characteristic factors in water, and make the treatment of water that exceeds the standard easier and more economical.

Seplite® MonojetTM CM1850 uniform particle strong acid cation exchange resinproduced by advanced "jet granulation" technology after repeated tests and demonstrations. By using the special structural design and functional group setting of the resin, the binding force between the resin and glucose and fructose can be differentiated, and the efficient separation of glucose and fructose can be achieved through the elution of spreading agent according to the degree of difficulty of separation.

On June 24, 2020, the National Property Office of the people's Republic of China announced the list of patent special research projects of 2020, it has 30 projects in total all over the country. Sunresin New Materials Co. Ltd., Xi'an and Sunshine Intellectual Property Group applied for the project of "Patent Analysis and Research on High Performance Adsorption&Separation Materials and Application Key Technologies", and the project successfully shortlisted.
